I'm a fan of electronics. I've been playing around with Arduino Nano and ESP32 boards. I decided to go ahead and make my designs more permanent by soldering them onto punched cards. The use of conventional helping hands did not help. I am generally satisfied with this board holder. It's pretty sturdy and the metal is where it should be. I'm afraid the screw pins will not hold up as they are not made of high quality plastic. Very durable rubber feet. Good buy, I recommend
