5x7cm DIY PCB Prototyping Perf Circuit Boards Breadboards (Pack of 10) by Envistia Mall

The copper plates come away from the fiberglass far too easily, they're single sided so that makes it impossible to use both sides of the board for circuit design and it makes soldering quite tricky in some cases too. They weren't that much cheaper than higher quality double sided dev boards. I'll stick to the double sided ones from now on.

I purchased these boards for their small size, and their price. They are not too big, and not too small. Perfect for what I have in mind to do with these boards. They will come in handy for my smaller projects.
