Uxcell 0 4X2 4 Hardware Alignment Screwdriver Review

Purchased to adjust the onboard voltage on my CR-10s 3D printer. Tip too big for driver potentiometer, suitable for power supply potentiometer

Another example of Chinese junk. The tip broke the first time I inserted it into the screw slot before I even turned the screw. Do not buy this POS.

I bought these to adjust trimmers on stepper motor drivers. It did what it was designed to do, nothing more, nothing less. Don't treat them like regular screwdrivers!

Good screwdriver when you need a non-conductive tool. The only thing I complain about is that the grip is a bit too big which prevents you from getting into tight spots to adjust or adjust, but I knew that happened.

The only thing I think it will be useful for is setting up the trimmer. I tried to loosen a small screw with a screwdriver and the tip of the screwdriver broke off immediately. So I can still use it to flip pots (I hope), which is cool, but I'm a little disappointed that it's a one-trick pony.

As long as you take good care of it and use it properly, this is a great product. I would recommend using this only for adjusting potentiometers and not anything that requires significant torque. This is an electrically safe screwdriver, but not a substitute for a real screwdriver. Aggressive use of this tool will break the tip.

I use it to set the voltage reference on stepper motor drivers. If it slips off the adjustment screw I don't have to worry about shorting something and possibly burning the board. There's a rotating cap on the top that you can rest your hand's pad on, and that part creaked horribly. I speak LOUD. My dog came running from the yard. A tiny piece of white lithium grease took care of that.
