Review on 🔵 GeeekPi Raspberry Pi 4B ABS Holder Breadboard 5 in 1 Base Plate Case for Raspberry Pi 4 Model B, 3B+, 3B, 2B, B+, Zero, Zero W, Arduino UNO, and Arduino Mega 2560 (Blue) by Bennie Boss

Serves its purpose and at a good price. If you've been messing around with the Uno and keep thinking it would be nice if things were more discreet and organized, this will help. My projects were easier to keep clean, and fixed points between the breadboard and the Arduino help with debugging. My only complaint, and it's minor, is that one of the rubber feet is off the corner. So when I put my hand in, the mount lifts up a few millimeters. It's not a big deal and I usually just put some Blu-Tac on that corner and it's no problem. You can also change the orientation so that this corner is up, but I prefer the Uno layout.
