I've only owned one lift, but this Eagle has served well over the years ... It'll lift my 3/4 pick up with a plow and sander on it, and has literally been up and down thousands of times ... It's got a strong set of locking pins for safety, so I've never had any concerns using it ... I'm sure there are better ones out there, but I've got no beef with Eagle ...
