hydraulic wheel dolly

I am looking at some hydraulic wheel dollies on EBAY that sound OK but am wondering if anyone has any experience with them or something like them. The link is at http://cgi.ebay.com/ebaymotors/ws/e...viewitem=&_trkparms=clkid=4916423406815477403
I have read some posts on HAMB about wheel skates but the ones on EBAY look better. Any opinions? I need to purchase something very soon and would appreciate any suggestions or experienced comments. Thanks much in advance.

 

They're all knockoffs of a product made by Go Jak...

bought my knock offs at Canadian Tire (Harbour Freight of Canada).. they work well, but are designed for moving a vehicle, then lowering it back to the floor, not for leaving them raised, like the traditional skates.. they work well, just be cautious of a sloped floor, as they have no brakes...

 

I'm ordering these shortly. Buddy of mine has them and they work very well. They are little more expensive than they ones you were looking at on ebay though.

Thanks a lot for the quick feedbacks. I'll probably go with the EBAY items.

 

I have a set of Gojacks and have used them alot--great item for moving car around,etc--but as someone said, let one down when you have car on them--car will take off rolling very easy
