Review: Junk - 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.
Review: Only good for lightweight work.... - Poor quality - 1st time I used it, the end became loose from the shaft. So it holds the bit, but the bit just spins freely. I guess not designed for any heavy torque usage.
