Review on 🔌 3220-Point Solderless Breadboard by Makeronics by Jeremy Flint

While initial thoughts were positive due to the solid construction and overall roomy layout, I found that the pins on the board are not 100% picking up signals as they should. I built a simple full wave rectifier circuit using a few diodes and a resistor, but I saw a strange waveform on the oscilloscope. The result shown in the left image is what was in the output, but it was wrong. It wasn't until I put my palm on the circuit and pressed all the components that the output became what it should have been, as seen on the right. After I stopped clicking on the components, the waveform went wrong again. I recreated the circuit on another board and it worked fine. Most likely, the reason is bad contacts on the board.
