The best thing Ive ever used, a great item for everyone!
After unpacking, two screws with plastic racks of the board mounting case fell out. I had to disassemble to restore the fasteners, at the same time I installed a switch and extended the network cable. The body is dry plastic. Very sensitive setting.
Pros
Compact, impulse, adjustable.
Cons
There is no switch, short wires, the board mount was broken off.
