After using it for two days, I don't really like it.
The bottoming out feels really mushy, the switches themselves feel like the unclipped stabilizers. It has a plate, but I think that the combination of thin plate and flimsy plastic case make it feel like ****. When I apply a lot of force on the keys, the whole PCB+Plate combo moves up and down inside of the case.
The cable placement is also a tragedy, it juts out of the top of the right side, making it interfere with the mousepad if you put it on the right and with the keyboard (if its TKL-Fullsize) if you put it on the left.
But for $11, its a nice little numpad for quick usage, and a nice object for taking pictures with
