I'm still using most of my Maximum socket set from around 2003. Built and tore down a few cars, used breaker bars, snipes on the ratchets regularly, using the chromies as impacts for years. Been wrenching full time on trucks and equipment since 2012 and they're now worn out...but still holding on. I think I broke a single 21mm socket using a 24" breaker and a 16" pipe.
Can't say as to the quality of the current socket sets though.
Maximum combo wrench set from 2012, I think it's the 12pc that always went on sale for $25 or so is still holding up as well, surprisingly. Sees use every single day with double wrenching and pipes. Some of the open ends have opened up, the small stuff under 7/16 is basically useless as an open end, but they're still kickin.
Honestly I haven't bought tools there in about 5 years so I guess this doesn't really help, does it?
