I work at a body shop and spent a hell of lot of money to what is now known as crap-on , the sets I bought a couple years back still work great but it just seems that there goin down hill quickly, gearwrench are great I haven't had no problems and I also picked up a dewalt 204 piece set at sears for like 200$ I believe and they been great we also work on semi trucks and these dewalts haven't let up no slips or breakage yet I've had them for about almost a year. I bought these just so that I can beat on them and plus there lifetime warranty also.
