Review: Little badass watch! - I bought this watch preowened, I never owned a smart watch until this product. Im not going to lie this watch is a tank! I do reccommend 44mm screen protectors! The battery life is great I wear it everywhere. Only thing is charging it is wireless there has been somedays where I didn't place it corretly on the charger woke up to low battery, but it still gets the job done. I am outdoor person so have even been fully submurged lakes there was no damage at all I take showers with it and no damage. I've also use this watch while mountain biking and I've slammed with it on still works! The outside the screeen glass metal has some wear on it, but I think it gives it flare like Boba Fetts armor. I bougth this watch to keep track of my fitness and has a bunch of great features and there is also one where you can use the watch to take pictures hands free! Lastly for my nerds yes I have downloaded the Fallout Pipboy watch screen on it pretty cool!

As others have mentioned, this watch came in the original box but the box was beat up. The watch itself is like new and if not for 1 tiny nick on the underside of the case that you can't even see while wearing it, you'd never know this was "renewed". For the actual watch, I replaced my aging Fitbit versa 1 and won't go back. I like the look of this watch better and because of WearOS, it has much more options. Sleep tracking isn't always correct for my wake up time unless I actually go into the sleep menu when I wake up so it knows to stop tracking if I'm just laying in bed scrolling through my phone before I get up. It's annoying but I've basically come up with a routine now that I set it for bedtime mode at night and when I wake up, turn off bedtime mode (which is really just DND and disables the screen from waking up with movement) and then immediately swipe over to the sleep screen. It is what it is. For all the other features, it works great and has a lot of options. Battery life improved for me after using it for about a week or 2. I get about 2.5 days out of it but usually throw it on the charger when I wake up for about a half hour while I get ready for the day.
