Review on CNBINGO Receptacles Electrical Tamper Resistant Screwless by Drexel Wortham

No instructions, it is not clear which wire goes where. I tried to figure it out myself, but then the following problem arose: the screws didn't even hold the wires in place, even when screwed all the way in, the wire came out immediately because the plate held by the screw was not fixed. Click on the wire. Tried to get it working but had to go back.
