87 reviews for T-Rex 3 Ultra Military-Grade GPS Smartwatch

  1. i***r

    I really like this smartwatch, the quality is very good. It has a sturdy feel and is made of high-quality materials. With precise gps navigation and motion data tracking, it can swim in the swimming pool without any problems. Easy connection to iphone through application support, with features such as answering calls, multiple sports modes, and customizable photo dialing. In addition, the watch runs smoothly without delay, whatsapp notifications are delivered instantly, and the connection performance is excellent. Highly recommended.

  2. q***r

    This watch can truly see the location on the map, and you can clearly see the map of your city on the watch, which will accurately locate your movement trajectory on the map. This surprised me a lot. Another surprise to me is that the dial of this watch can be generated by artificial intelligence and is free of charge. This is what i think is a very unique feature of this watch. Other watches have dials, but only a few dials are available for selection. If you want to wear additional dials, you will need to pay. I think this smartwatch is really cost-effective (with built-in gps, waterproof swimming, bluetooth calling, large capacity battery, health monitoring, etc. ).

  3. j***r

    In short: recommended purchase with high cost-effectiveness. After wearing it for two weeks, i discovered that it was a practical smartwatch. In sports mode, gps synchronization speed is extremely fast and activity tracking is precise. It has a very clear and bright amoled screen, and the battery can last for dozens of days without charging, making it very suitable for daily use or exercise, fully recommended.

  4. Customer

    Great quality price. Everything works perfectly

  5. D***l

    Top quality and fast delivery

  6. e***r

    I like swimming, so i wear this watch while swimming and asked a friend to take some photos of me. After being in the water for about an hour, the watch still works perfectly, as described by the seller. The 6-axis sensor feels reliable, and the swimming data is accurately recorded throughout the entire process, making everything look stable and consistent. My friend who helped me take photos even asked me where i bought the watch, and i have already recommended it to him. Overall very satisfied, strongly recommend to sports enthusiasts.

  7. J***k

    Really OK

  8. j***r

    Okay, i usually don’t comment on what i buy, but it requires expressing my thoughts. This smartwatch is really amazing, its gps positioning speed is very fast, and the screen selection is very smooth, almost unreal. You can also create your own watch face. Everything about this project is great. For this expense, i had hoped to get a decent smartwatch, but what i received far exceeded my expectations. Thank you seller!

  9. Customer

    Excellent product. It arrived before the scheduled date.

  10. w***r

    Thank you very much for providing me with a very good multifunctional smartwatch. I like hiking, so i really like its built-in gps function, which provides high-precision gps positioning and tracking history. I think this smartwatch is really cost-effective (with built-in gps, compass, altitude barometer, bluetooth calling, 10atm waterproof level, health monitoring, etc.). I am very satisfied with this smartwatch. Wishing you a prosperous business.

  11. Customer

    Evaluation after 24 hours of use. I really liked the quality, it arrived quickly and was very well packaged. I synced with Poco X5 Pro, GPS working accurately. It came with 2 manuals due to the large number of translated languages, including Portuguese (Brazil). I also synced with the Strava app, completed the activity, and it was successfully recorded. It also mapped my sleep by assigning light, heavy, and deep sleep scores. I took a shower with it, and as soon as I got out, the watch itself activated the water drainage mode. I found it sensational. Heart monitoring modes, among others, as well as a very interesting barometer and altimeter. The flashlight is very powerful. His app on the phone is also very intuitive. The quality of the strap is very good, as is the rest of the watch. There is a YouTube video that shows all its features, just search for KC91. I’m going to buy another one to give as a gift to my son.

  12. w***r

    I chose gold for myself and black for my husband. Gold looks really beautiful, not glamorous, but shiny enough to make my clothes look fashionable. Good quality, easy to set up! Overall, i am very satisfied with my appearance and work style, and my husband also likes him very much.

  13. g***r

    This watch has a very beautiful case and a very novel and unique design. The battery capacity is really large and can last for a long time. The flashlight is also very bright and the compass is very accurate. I like the bluetooth call function and the health monitoring function the most. The packaging is not damaged and the delivery speed is very fast. I recommend it

  14. h***r

    Beyond expectations. Top watch

  15. J***a

    Nice watch, something basic but not bad for the price.

  16. Customer

    Fast delivery, Korean language support, and good phone connection. It’s a light and decent perfume.

  17. Customer

    I really liked the watch, fast delivery

  18. Customer

    The product was refunded because the description stated that it was original, but it was not.

  19. N***d

    Meets expectations

  20. Customer

    GPS doesn’t work, I don’t recommend it.

  21. Customer

    Good product

  22. Customer

    It’s not the original smartwatch, but what more can you want for this price? That’s all there is to it. So far it’s been tested. And it definitely won’t last as long as they say on battery life. Max 5 days.

  23. p***i

    Excellent, but the straps are very fragile. I will comment on the durability. Later, its functionality is okay.

  24. E***d

    Its some years since last time i baught a watch from kina. Im quait happy with this watch, and will buy it again. It has options that my old garmin watch didnt have. If you considder the pris its a no brainer.

  25. M***o

    Exceeded expectations, very high performance!

  26. Customer

    Something lightweight but of relatively good quality, it has an altimeter and barometer as stated in the description, quite acceptable.

  27. Customer

    Very good.

  28. Customer

    Great watch. It looks really nice, and the app is also good.

  29. Customer

    everything is fine, perfect watch

  30. T***g

    I’m actually very impressed by the quality, responsiveness, and functionality of this watch. For the price, i definitely recommend it!

  31. Customer

    The watch comes with a flashlight, chat gpt and has a bright display for the daytime, it aslo comes in with 2 manuals on how to use the watch with many different languages. The watch is super light,

  32. a***r

    Functionally, the watch works perfectly. But on the wrist, you feel that it’s cheap. The dials also look cheap. Optically, the watch doesn’t impress at all. I won’t wear it. I’ll give it to someone as a gift.

  33. Customer

    Excellent watch. Super fast delivery to Brazil. I haven’t tested the GPS yet, but it’s green on the screen (connected).

  34. Customer

    The T-Rex is great, it has so many features that I haven’t tested them all yet, fast shipping. I recommend it to everyone 🤗💪

  35. Customer

    excellent product

  36. Customer

    Everything was resolved without any problems (the product was returned to the seller).

  37. c***d

    It doesn’t even hold the 3m depth of the pool. I went to the pool and the next day the marks appeared on the screen, and in addition, the background kept changing. for 2 days. The line no longer appears. super disappointed

  38. A***e

    The watch looks great, decent price and it was very easy to install the app. it works great except it shows celsius not farenheit in spite of all my trying to fix the problem. the gold metal band i could not extend for my hand and the customer service is helping to resolve the problem.

  39. Customer

    Great watch strap. I recommend it to everyone 💪

  40. Customer

    Does the job, very practical during sports sessions. It would just be missing a GPS version of the sailing sport with speed and tracking information on a map, like for running.

  41. M***a

    It is advertised as a T-Rex watch but it’s an imitation, it’s a Kc91, although that was to be expected given the price. I can’t see the GPS route on iOS until the workout is finished: still, it works for what I need.

  42. Customer

    I am not satisfied with the watch because I received some kind of stripped-down version. There is no pressure gauge. There is also no altitude meter. I bought from another seller 2 months ago and it had all these features.

  43. Customer

    He sent me the watch without a charger and without instructions, terrible.

  44. Customer

    Great, my husband is satisfied, the smartwatch is touch-sensitive, has many functions, and the GPT works very well. I recommend it.

  45. G***i

    I recommend this store, everything went smoothly and quickly.

  46. 1***r

    — The product was delivered without any issues. Everything is correct, good product. Everything perfect.

  47. Customer

    For that price, it’s really worth it, although I haven’t tested everything yet.

  48. Customer

    The watch features an elegant design with great attention to detail, making it visually very appealing. Its performance is precise and reliable, with no issues encountered during use. The product arrived well-packaged, reflecting care in shipping and attention to the customer. Overall, it is a highly satisfying purchase that i would confidently recommend.

  49. Customer

    Made of good material, good value for money.

  50. R***r

    Great watch, does everything i wanted

  51. Customer

    The watch is acceptable, everything matches the picture.

  52. A***s

    Everything is fine, except for the delivery driver’s fgp. He plays on top of the gate. Be careful.

  53. l***r

    Good smartwatch

  54. Customer

    This watch is amazing, the GPS is quite accurate and connects quickly.

  55. G***i

    A smartwatch with many functions and well-made for the price paid is also too much.

  56. g***n

    I am very dissatisfied with the incorrect description. The watch is stated to have 10 ATM water resistance, but it only has standard IP X8 as shown in the picture. These are false claims.

  57. Customer

    Very nice functional watch and delivered quickly!

  58. Customer

    Just what i expected will test and come back to review more Thanks

  59. Customer

    Honestly, a smartwatch at this price with all the features and such responsiveness… I recommend it.

  60. V***E

    It’s very good even though most watches are not compatible with iPhone; it provides its basic services very well, such as WhatsApp and messages, calls.

  61. Customer

    Surprised by the quality, very intuitive, seems solid, and despite being large in size, the octagonal shape fits perfectly even on normal wrists. Fast shipping.

  62. Customer

    The watch is amazing. it does everything as described. great value and the seller made it a trouble free transaction. five stars all round.

  63. Customer

    It’s not a T-Rex 3, but it’s still a good smartwatch for its price.

  64. B***i

    Watch didn’t display despite multiple hours charging…item received broken!! filing a dispute!

  65. Customer

    My son is very happy with it.

  66. F***z

    I bought it for its water resistance. The specifications indicated 10ATM. Swimming activity. However, it is actually 3ATM. Only suitable for splashes and little else.

  67. Customer

    Super

  68. Customer

    Great watch, ideal and powerful flashlight… menu system is a 10 out of 10.

  69. Customer

    Arrived quickly, easy to set up, seems well-made, let’s see how long it lasts, nice idea with the light.

  70. Customer

    This is a scam, not a watch, it has nothing to do with the T-Rex 3. I regret buying Tandeta, it’s a waste of money. I was tricked into giving it 5 stars, it’s not even worth giving zero.

  71. Customer

    What arrived was not the Rex Ultra, but something completely different.

  72. Customer

    Battery level is 69% after 1.5 days. I don’t think I can hold on for a week. The rest of the features are useful. The thickness is thicker than the original, and purchasing additional charging cables or straps is a bit expensive. I’m not sure if the specs are correct. The GPS works well and has good features.

  73. Customer

    I like this watch very much. the build quality is greate, and the functions are working very well. the battery life is exquisite, one week is the norm. the gps function is surprisingly good. i highly recommend it!

  74. J***e

    It’s the same as in the advertisement, quite a few exchange screens and I’m testing the rest. Apparently the watch is good and useful.

  75. Customer

    For the price,this thing is amazing.

  76. Customer

    As advertised. Works very well, touch screen, no lag.

  77. 0***r

    I ordered the one in the picture and received a completely different one, gigantic and nothing like it.

  78. Customer

    Seems good , not tested in water .

  79. Customer

    work perfectly

  80. Customer

    The watch arrived quickly, the product is exactly as shown in the pictures. It works well. I recommend

  81. g***r

    I don’t think it’s worth the price I paid.

  82. Customer

    Beautiful

  83. 0***r

    This is the second time I’ve ordered it and they sent me a completely different model. I ordered the white and gold one twice, and both times they sent me this model, which is also a huge piece of junk. In the first order, I bought two, one black and the white one; the black one was perfect, the correct model… the white one was not.

  84. j***j

    It’s a counterfeit of the worst quality. It was never TREX, let alone the ultra. It’s not waterproof, it’s just resistant to water and that’s it. I’ve already requested a refund, you thieves.

  85. Customer

    This is not a T-Rex, it’s a distant copy, it’s some kind of KS91 model. It’s a shame that the seller didn’t mention this; I’m very dissatisfied.

  86. Customer

    Very good product

  87. F***r

    Very nice smart watch works in France with the Da Fit app on Android relatively lightweight for its size, sturdy and waterproof Satisfactory autonomy for the price GPS quite accurate, good point surprisingly powerful flashlight varied and cool dials I don’t use the AI part, not interested. otherwise I recommend
