Amazfit GTR 4 Smart Watch Fitness Watch Sports Watch with 150+ Sports Modes, GPS, Bluetooth Call & Music Control, 14-Day Battery Life, Alexa Built-in, Nylon Black

This is a great smartwatch from a growing manufacturer, with comparable design, build quality, and functions to much more expensive models. Very light weight with a fully adjustable strap, waterproof, and over 150 sports modes it is ideal for day to day routines. Very stylish as a formal watch and rugged enough for sporting activities. It can make and receive Bluetooth calls which saves on getting my phone out. Had this for just over a week and I am thoroughly impressed with it, battery life is great so far, but has not been fully charged yet, but I do use the GPS everyday as part of my exercise routine. This is a sound buy for an everyday smartwatch with all the functions you will need.

Easy to use & plenty of info to pick through. Like the sleep data.

After using for almost 2 months I am reluctantly returning the watch. It has great features, good looks and UI, altho the app UX should be simplified.My main issue stems around the general over sensitivity of the touch screen and button. All activities I do, get interrupted by this issue either pausing or stopping itself all together or playing music. Or auto replies when showering. The GPS is accurate but Ive been through a period for 2 consecutive days where no amount of troubleshooting made the built in GPS to connect and work (hence your run is way off accuracy). I do wish that it was more reliable, as the price Vs value is otherwise very competitive. For me, I will prefer to now choose an equal or cheaper priced option but with less features and more reliability.

Useful smart, sport watch

I have owned the original GTR (5 stars) for a few years and have been very happy with it. Unfortunately it has come to its end of life and needed to upgrade. The logical step was to buy the GTR 4. Here is my review:I use the watch mainly to track my exercises: walking, running and cycling and this is the real reason why I give it two stars.Pros:- Cost.- Brilliant battery life.- GPS is much better.- Navigation is a game changer. Nice to be able to set a new route and follow without having to get the phone out all the time to check where I am going.- Can connect external devices like heart rate monitors, etc.And that is where the pros basically end.Cons:The biggest con for me (someone that exercises) is that the sensors under the watch don't switch on if it doesn't detect skin. I got confirmation from support that the watch will first try and detect that it is on skin before it will switch on the sensors. Great in theory, but it doesn't detect skin all the time so doesn't switch on most the time. Even more of an issue if you are like me that has tattoos down both arms. Seems to make it worse.With the original GTR, when the watch wanted to read your heart rate, it would switch on regardless of if it was on your arm or not and would always pick up my heart rate through my tattoos. I can't see why the GTR 4 can't be set to do the same. When the GTR 4 sensor is on, it can also read my heart rate through my tattoos without any issues.The same goes for sleeping. The GTR 4 doesn't read my vitals while I am sleeping so that is also now a waste of time. The original GTR didn't have an issue with this.For me and I am sure that for anyone else that exercises, tracking ones heart rate is a vital part of ones training. At the end of the day this is a real let down. I have had to resort to using an external heart rate monitor strapped on my arm next to the watch to log this.To Amazfit, stop trying to add a million ways to exercises and focus on fixing this fundamental flaw.
