Good cost / benefits. Connection cable 60 cm rather rigid: the miniature connector (a priori fragile) housing output could be easily damaged if the cable had to bear recall effort too strongly curved (I maintain a radius of curvature of about 20 cm). The tray-shaped lid barely slips: it is particularly painful to open because there is no outlet for the first millimeters. When the drawer a household outlet, a little too lively traction makes you run the risk of a sudden and complete opening (with the burst disc is locked there).
