Have only had 2 Duralast tools, a 24mm wrench that I use daily (mostly alignments) and a 3/8" 10mm deep socket (backup, barely used).
The socket has shown little wear from being used on my 3/8" impact, whereas a Craftsman I used for the same purpose wore out rather quickly.
As for the wrench, I've had a 5 foot pipe on the thing before and it has yet to break/bend...hell, it doesn't even have any chrome chips, surprising given the abuse.
Take that as you may. Personally I prefer Craftsman if I'm going 'low end'.
