Save your money and just say NO!!!
I got a set of those more than awhile ago as part of a buy one get one deal, and I think they **** but, that's just my opinion.
For starters, they're friggen huge and kind of heavy. Below is a Gearwrench 18mm ratcheting crowfoot compared to a regular Snap on 18mm crowfoot. 18mm is a common size for power steering fittings at the rack. Additionally, the Gearwrench ratcheting crowfoot is laser etched. Nothing is engraved or stamped aside from a little arrow indicating ratcheting direction. Another thing I can't stand is that Gearwrench cheaped out and doesn't have cutouts or a hole for the drive tool or extension retention ball in the female square drive. even if you used a locking extension, there's nothing for it lock into so, the ratcheting crowfoot falls or slides off with ease.

Lastly, the set is made in the PRC which isn't my favorite production location for Gearwrench tool.
The ratcheting comes from a spring loaded pintle that engages a flat on the fastener. You need a fair amount of swing to use it. I'm not impressed. I own and use a lot of the Gearwench line but, these ratcheting crowfeet are not one of their best efforts. The tooltopia ad seems like a good deal but, I feel you could spend that $44 on anything else and be better off.
