amazfit bip Built with a matte-textured plastic chassis, the Bip transitions nicely into a slightly curved slate of Corning Gorilla Glass on top of its colored, pixelated display. Moving around the tracker’s interface is done on the touchscreen, but waking it with the side button is mandatory. This design choice might seem like an annoyance, though it’s defensible when you realize how easy it can be to accidentally swipe the screen when you’re working out.If you like amazfit bip , you can buy it from Tomtop.
