GOOD product thanks

I use such cards for a long time, a good choice for the price applied. Very good plastic moderately smooth and pleasant to the touch. Reliable contact pads, but over time they become loose and can even fall out if children strongly press on inserted chips, there were a couple of cases. The colored mark of the polarity of the power supply is erased with time.

I bought these so that i could do more than just one thing at a time. now I have to buy a bigger board so that I can place them all together (2 rows of 5 boards)

Protoboards are excellent for SMALL projects but the attaching tabs don't line up for attaching boards together for LARGE projects and that is what I bought them for.

Works just fine. I've removed one of the power rails and joined two breadboards together - just right for working with ESP32 development boards which are too wide for a single breadboard.
