Review on Waterproof Positioning Two Way Compatible Android（Black） by Bryan Crayton

I'm glad I bought this watch for my 5 year old son! It's his first year of kindergarten so it's a great way to track his whereabouts. What attracted me the most was the safety of this watch. Of all the kids' smartwatches at Revain, I stumbled across this one because it's waterproof and I really like its simple style. They're not as bright and colorful as other kids' watches, which makes them pretty cool! You can make calls, send voice memos, track location, take photos and play games. But don't worry, there's a Do Not Disturb mode you can turn on while they're at school so they won't be distracted. It's also easy to set up, all you have to do is simply download the app on your phone and scan the QR code on the back of the watch. I am using a Speedtalk 2G SIM card for the installation and activation only takes a few minutes (SIM card not included - you need to buy it separately and make sure your location is covered by 2G network). small error with real GPS position due to signal condition and 2G network latency, so don't worry. Once the 4 signal bars appear on the watch, this is the most accurate position you will get. The watch also comes with a charger that charges very quickly. But most importantly, they have really great customer service! My son's watch strap broke on the second day of wearing. The seller contacted me quickly and sent a new replacement the next day! Talk about great service and reliable seller!
