Review on CZH-LABS Electronics-Salon Prototype Shield Kit for 🛠️ Raspberry Pi - Ideal for Breadboard DIY Projects by Jayt Shields

The boards themselves are made of a nice thick FRN and the headers, screws and racks are of good quality. I wish the screws were 2-3mm longer but they fit well. I also like the layout of the board with rails for 3.3V and 5V and a ground rail on the other side of the board to avoid potential short circuits. My only real complaint is that the pads aren't particularly durable if you need to remove components or wires after soldering. With my iron set at 400°C I tried to move the part of the pad that I had placed in the wrong place and I managed to pull out two of the four pads it was soldered to. I'm not new to soldering so I have reasonable expectations of how much heat and force I can apply before the pads tighten and this turned out to be easier than I expected. All in all, if you get the components right the first time, you should be happy with these boards. I can also confirm that they work great with the Pi Zero and Zero W and that the posts closest to the GPIO header align with the Zero's screw holes for mounting.
