“Jig could do with a better set of instructions. The force required to insert the Male Header is quite high, so better stability in the jig would make life easier.”
“I've misplaced my soldering iron in a house move, so ordered this to try out. It is so simple to use and so far rock solid connection to the pi. I'll very likely just use hammer headers from now on.”
“Not sure if this is only an issue with the Pi Zero 2, but the force required to get the pins even partly into the board seemed far too high. Even after increasing force applied, could not get the pins in to the board in an acceptable manner at all, with either the board bowing or the headers entering at an angle. Don't bother with this product - just buy some standard headers and use a soldering iron.”
