Version Update: V2.0 has upgraded its motor driver IC, it replaces HR8833 with TB6612 motor driver chip. TB6612 has the same control logic with L298 motor driver. The code will be compatible with Romeo robot control board. And it finally breakouts 2 interrupt pins now! You can connect encoders to make PID motor control.

Works as intended
Style: Black 6 Pack, Size: 7.25 inch
It works as it should. I does look like it bends down after screwing to the wall but the level seemed spot on. Either way it hold up my shelf great

Fantastic slimline brackets
Style: Black 12 Pack, Size: 9.25 inch
We're hanging some shelves that will hold some weight and wanted a minimal amount of shelf to show. It's about what's on the shelf, not the bracket. The black metal adds just a touch of style against the white painted wood shelves. They look great. The best part is that the screws go right into the middle of the shelf which makes it easy to hit the center of the stud. Standard box store lumber fits perfectly. A 1 x 10 fits like a glove and the small lip finishes off the classic look. Comes with all sorts of mounting hardware and the screws are decent quality and went in with no issue or stripping. I usually have to buy better screws but these were fine. At this price it really was an excellent deal and they are heavy duty. Win Win Win.

Fits Logitech K950 keyboard
This case is good for the Logitech K950. It is a no-frills zippered semi hard fabric case. No mesh pockets inside, no room for that. There are two mesh pockets on the outer top, but I would not trust them to keep anything heavy secure, nor IS it secure. Those seem more of a gimmick to me. My concern was to protect the keyboard, and the case does protect that.
