Review on Klein Tools Electronics Screwdriver 4 Piece by Max Rosengren

For work I make electrical switchboards (as shown in the picture). A screwdriver along with wire stripping tools is my most commonly used tool. At the same time the largest tool screwdriver; 4 inches; lived only 3 weeks. The tip has broken off and no longer holds in the grooves. We use 6mm terminal blocks and when I first got these screwdrivers I noticed that they have small heads. As if they were designed for 2-3mm terminal blocks, but after a few weeks of use this tool broke, and all other screwdrivers are even smaller than this one. So I can only imagine that if I start using them, they will also break. The worst thing is that I have a cheap nameless tool screwdriver that one of our suppliers gave away to all my employees for free and it still works. Why do brand name fools break when cheap Chinese ones last for years? Is there a way to get a refund or buy a new screwdriver? Does Klein make tool screwdrivers that fit 6-8mm terminal blocks without breaking? I could just switch to Snap. If I'm going to spend $15 on a screwdriver, I want it to last at least a month, right?
