## Customer Reviews

### ⭐⭐⭐⭐⭐ Junk
*by B***L on October 19, 2024*

I finally had to use these extensions. Right out of the bag, 2 have broken chucks, they do not lock the bit in. And they don't spring back closed. These are garbage and a complete waste of money. I feel stupid for not testing them when I received them. Folks, don't make the mistake I did buy these.

### ⭐ Junk
*by M***O on September 19, 2025*

Absolute junk. The head stripped out and started spinning on the the 1st screw I used one for. It was just a 1 1/4 screw into a 2x4. Do not waste your money. Terrible value for money.
