Anywhere? car lift

Looking for some one who has either heart, seeing or have experience with the EZ car lift – www.ezcarlift.com (http://www.ezcarlift.com/) I am looking at purchasing one. I saw it on www.gotogroupbuy.com (http://www.gotogroupbuy.com/) – item 229. I like very much the concept of being small and light. It looks like it has wide open space and will give a lot of access to the underbody. Does it really work like the floor jack as they say on the video? Could it really be used any where as it is a free standing unit. The manufacturer claims that it can be used on any surface, ya right!
