Harbor Freight 6000 Lb. Capacity Scissor Lift Review, Central Hydraulics, is it worth it?

I have one of those lifts 110V I bought from a friend who bought it from his friend. Don't know the brand but it was perfect for helping build my Barracuda. It is now being used to build an off road bronco and the guy I loaned it to loves it. It just makes everything easier. It does take some care setting it up properly though but once correct is very stable and safe.
