"Saw the bad reviews for this nut driver, so next time I was in store took half inch socket, and helpful staff allowed me to fit it before buying, (as I explained about the bad reviews). Fitted no problem, so perhaps a different batch? Works just fine."
"This SDS+ bit doesn't even fit in my Bosch SDS+ drill. It looks very similar, but it's impossible to push into the chuck. You can knock it in with a mallet if you're desperate, but be prepared for fun and frollics getting it back out again."
