Review on 🌈 Smart Watch: iPhone & Android Compatible, Fitness Tracker with Heart Rate, Sleep & Blood Pressure Monitor - IP67 Waterproof, Step Counter Sport Smartwatch for Women & Men by Justin Olson

I ordered two of these watches (black and silver) and the silver one came with no holes to attach the strap? So I sent this watch back and received a replacement that was properly assembled. The software speaks for itself and the watch syncs well with the phone. I used a notifier for messages from phone to view and it works fine. All in all a decent value. The Revain video seems to show that there are many watchface settings, but only the display changes (sub-functions like BP or heart rate cannot be changed). one star off my rating.
