Great product
Great extensions. My favorite tool brand so far. Good value and the locking rings hold the sockets nice and tight.

Great design, works well
Addresses a problem with extensions, sockets fall off in worst places. This extension locks sockets in place without adding any bulk to the extension. Highly recommended

I would buy them over and over again
Even if one breaks, if you fill out a warranty slip on the GearWrench website - they will send a replacement as quickly as they can. Great customer service and great tools. I use these extensions daily.

Don't lose your sockets anymore!
Work exactly as advertised. The female end is even a little snug & doesn't fall off of my impact like others have. The black phosphate coating does seem a little harder to clean than something gloss, but, enough brakekleen will get through anything.

Not for at work. Locking is questionable.
Sockets either barely lock on or don’t, not for professional use at all.. use em a few times at home ya ok. also broke internally after being on my impact gun and couldn’t get a socket to come off, these and the 3/8 set I bought are junk for at work ..... spend top dollar on snap on and they come replace my broken tools provide a better product from start

They are good quality and work as needed.
They work as intended, not much more to add.

They work well.
They look like good quality. Another affordable alternative to buying overpriced snap-on. They should hold up fine.
