My wife and I (both fairly tech savvy) struggled to get this "smart" watch to pair and sync with her Samsung Galaxy 8 Note. Documentation is non-existent (the little bit they provide is 6 point type, broken english, and more just "what colors are available" than anything useful to setting up your watch. The QR code for set up is literally 1/8 square -- no QR code reader I know of will be able to make any sense out of that). No documentation online (best I could find, the company doesn't have a web site). Once we finally got it syncing (mostly), found the displays very limited (options seemed either numberic, or Chinese - we think). The kicker that made us decide we were returning it was when, less than 24 hours later, the screen locked (see pictures) and wouldn't come off. Very disappointed (had seen other reviews, but as the Amazon Support Representive I contacted pointed out, they were all over a year old). Apparently, if you have an older phone, it works okay. Not our experience with a newer, high end phone. https://smile.amazon.com/OURSPOP-Bluetooth-SmartWatch-Monitor-Christmas/dp/B0776C92DM/ref=pd_rhf_dp_p_img_1?_encoding=UTF8&psc=1&refRID=N349PXSN3GN2TBJH11RT #RankBoosterReview #OURSPOP
