Review on Gikfun Solderable Breadboard 5PCS Kit with Gold Plated Finish - DIY Proto Board PCB for Arduino (GK1007) by Fernando Ramani

The purpose of buying a soldered breadboard is so that what you have on a breadboard can be fitted with a solder joint. The hole spacing is normal for the columns marked "a" through "j", but the hole spacing is completely OFF on the +/- bars on either side. The end result is that my Hiletgo ESP32 module fits perfectly into the holes in columns b and i, but the MB102 breadboard power supply does not fit into the +/- holes on the left and right sides of this so-called solderable breadboard. I had to cut the pins on the right side of the MB102 to at least fit the left (5V) +/- holes. This means that only one side is connected to the MB102. Too bad because that should be a 5 star rating. It got 2 starts just because of the quality. Now I'm stuck with 4 faulty solderable "breadboards".
