I have one like the above and it is perfectly serviceable. I don't
suppose it will last as long or be as good as the pro ones at 10 times
the price, but are they 10 times better? I doubt it. It makes holes.

Grr, shame I didn't bid on it before it was too late!

What is the difference between SDS and SDS Plus anyway?
If they all fit into the same drills, why the two types?
