I don't have any first hand knowledge of those products, BUT, the good thing about Costco is that as long as you keep the receipts you can return ANYTHING, and quite a long time after the purchase as well. If you're thinking about getting it, just get it, if it turns out to be junk, take it back, no problem.

I'm looking at a hydraulic racing jack at Costco so that I can get under my Vette when I need to, just haven't had the time to go pick it up.
