I found coupon on Tinwootech.com web site and was directed to Amazon to purchase. With coupon it was about $30. GREAT BATTERY LIFE. I'm currently at about 50% battery power after charging it one week ago. It came with USB cable with magnetic contacts to charge it but I haven't used it yet. I've been using wireless charger for my Galaxy S9+ and it works great. I saw many complaints about bluetooth connection issues but so far I've had none. I followed initial setup instructions and paired it inside the watch's app I installed in the phone (they say don't pair it using phone's bluetooth app). The phone and watch disconnected from each other when expected (reboot after Android update and when I took watch off to rip out some weeds and bushes in the yard). They paired right back up again when back in range. Just a few minor things I'd like to see improved. I wish the weather forecast on the watch showed percent chance of rain - it shows relative humidity (seems odd to me). The swiping directions (up, down, left, & right) and menu options could also be better & make more sense, but I'll cope and get used to it. The vibration used for notifications should be stronger (IMHO). Recommended if the positives outweigh the negatives for you. With excellent customer service and return policy from Amazon & Tinwoo it's definitely worth considering.
