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.

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. ).

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.

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.

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!

Excellent product. It arrived before the scheduled date.

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.

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.

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

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

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.

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.
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!
