HF and Sears appear to use the ame supplier. So why not splurge and get the HF aluminum version? It's the same as the Crapsman (Craftsman) jack. I've used mine a dozen times with no real issue. My only complaints?
* It has a hair-pin release. Be careful turning the handle.
* It has about 1/4" floor clearance. Mine hangs up on the transition between the drive and garage.
