good product, has many features, very helpful for sleep tracking, and has many other helpful features like tracking steps and other exercising tracking, heart monitor, not sure if that's accurate but it is cool as well, there are some features that could go without, like the flappy bird game, although neat, but could have been a better useful feature, although it's not terrible since it doesn't get your attention so it doesn't give crazy amounts of dopamine, but a small way to pass time, helps even more that it is just that, and doesn't have a highscore thingie to further get sucked up, i would like if there was a (inactive) feature, i wear this watch all the time, i wouldn't want it tracking steps and cal lose if I'm not moving around, but tracks movement like small ones, wouldn't want that to count as steps, other that that i love this watch, it has helped a lot, even to look at the time quickly without grabbing my phone from my pocket, and it emits little to no blue light, would like if the side button also let me turn the screen off rather than just waiting for it to turn off, definitely 3 stars worthy ❤️
