Installing the stabilizers were pretty difficult. I usually prefer screw in stabilizers, but used the ones included (they look like the WS Stupid Stabilizers). I was unable to install the tiny clip in inserts on the bottom side of the PCB because they were so small for my hands. So far nothing bad has happened to the stabs yet which is good.
My configuration came with a PC plate, and the holes for the plate and PCB standoffs were not screwed holes, so I had to forcibly push the standoffs into the holes. Having screw in holes so I can screw in the standoffs would be better, though this might not be possible for softer materials like PC.
The screen seems to be a little loose on the top frame. It's probably not going to come off, but if you tap on it, there is a bit of rattle.
The ribbon for the scroll wheel is a little too long and I needed to fold and crease it to get it to fit into the rubber bumpers. Hopefully this doesn't damage the connection long term. The wheel is also a little stiff, which may be intentional to prevent accidental scrolls?
