The wireless memory key is about the same size as a highlighter pen. A cap protects the USB adapter and contains a clip that lets you attach the WLBZ201 to the inside of a jacket or other pocket.
The USB plug is connected to the wireless stick via a moveable hinge, meaning that the integrated antenna can be swiveled up to 90° and turned in nearly every direction. For the test we kept the swivel part turned straight up in order to maximize the emission-receiving/emitting surface. Thus we were able to achieve good signal quality, even through two closed doors at a distance of around eight 8 meters.
