I have about the unit decided before now a month after I short a prized investment sought. After I looked around on the internet and the reviews there seemed convincing I ordered the device and get to have 2 days .. The device is easy to use, the measurement results appear realistic to me and are also available later. Of course, measurements on the upper arm even more meaningful, but I needed a small, compact device without many accessories. With the scope of supply includes the required battery, a comprehensive manual and a plastic box for storing and transporting. I would buy the device Weider.
