Okay, so I've been using this fitness tracker for about 3 months now and here's my totally unfiltered take on it.
First off - the design is sleek AF. I was worried it would look bulky but it's actually super low-profile. I wear it to work meetings and no one even notices it's a smartwatch.
The heart rate monitoring has been scarily accurate? Like I checked it against my doctor's office equipment and it was only off by like 1-2 BPM. The sleep tracking is my favorite feature though - seeing how much deep sleep I get (or don't get) has actually made me change my bedtime routine.
Battery life is insane. I charge it like once a week while I'm showering and that's it. Though warning - there's no low battery alert which kinda sucks when you're out running and suddenly realize your watch might die.
The waterproof claim is legit - I've worn it swimming multiple times with zero issues. Though pro tip: dry it off after because water droplets make the touchscreen act weird.
My only real complaint? The band sizing is confusing as hell. Had to return my first replacement band because apparently '22mm' doesn't mean what I thought it meant. Measure twice, order once people!
For under $20 (got mine on sale), this thing punches way above its weight class. It's not an Apple Watch killer, but if you want basic fitness tracking that actually works? 10/10 would recommend.
