But I was super surprised by the size of the object. I imagined much larger, in fact, it fits in your hand, it is very small. Without reading the instructions, you can easily get to make ultra-precise measurements and ultra fast ... I never measured my apartment (some are 7m long, not practical with a measuring tape!), It's done! And to have it always at hand, a pocket for attaching to the belt is sold. Batteries are supplied .... And it communicates via Bluetooth .... short, he is still missing something? I do not think so.
