4 pieces vary in quality. One of the frequently gets jammed as the spring is quite thin. Nothing compares to my original shown in 1st photo. They don't make them like they used to.

Worst tool purchase ever... The end is too big and does not fit in the hole we'll. The part that slides in the other goes in then gets stuck each time. After just a few holes, the spring was destroyed. Also, the bit comes out and you cannot tighten enough to keep it in. Other than that, great LOL
