Before that, I only had Xiaomi Mi Band 3 and Mi Band 4. I estimate based on this experience :)
• Looks great. Expensive, stylish. Materials class;
• Sapphire glass. On the Internet they write that it can only be scratched with a diamond or diamond, but is less resistant to impact than mineral glass;
• The strap is very pleasant. I was surprised by the special fasteners thanks to which the strap can be easily removed. Haven't seen this before;
• If you buy a leather strap, then this mount will allow you to quickly switch between straps depending on the occasion;
• The fluoroelastomer is very pleasant. Soft, does not rub at all;
• About a hundred different screen themes;
• There are functions: notifications, calls, contacts, answer a call, pedometer, moon phases, illumination on the ground, heart rate monitor, compass, barometer, heart rate monitor, maximum oxygen (VO2 max), sleep quality, stress level, barometer, compass, weather, stopwatch, timer, timer, alarm clock, flashlight (just makes the screen white, no diodes). I could have missed something because there are really a lot of functions;
• A lot of training modes: aerobics, yoga, running (different modes), cycling (different modes), swimming (+ modes), skiing, snowboarding, strength training, martial arts, even dancing, even swings, different sports (bowling , rugby, etc.). In short, more than a hundred different modes!
• Built-in speaker! You can listen to music directly from the watch;
• Given the water resistance, you can also listen to music in the shower. Sing karaoke :) Although, rather, it is necessary to upload audio training programs (voice of the coach);
• To the music of 2GB of internal memory (I don't know why they write 4GB on , I have 2GB);
• The device can be turned off! Directly completely (for example, this was not the case on mi band). This requirement may arise in aircraft, medical facilities, blasting sites, storage and use of combustible materials;
• A good application, where you can see the statistics and adjust your settings (weight, goals, heart rate thresholds, etc.);
• Wireless charger
