"I bought this simple, easy to attach adaptor to fit a keyless chuck to allow me to use all my standard drill bits with my newly purchased SDS+ drill. Just remember the thread of the fixing screw is left-handed! Excellent."
"Bought 2 of these in one week. The screw that goes in the top wears down after one use. The last one I had the screw wouldn't even come out. I bought the chuck for this also and one of the prongs inside got stuck down and that's the end of that. I couldn't even be bothered to return it as it wasn't worth while in fuel. Manufacturing needs improvement."
