The lift controls are mounted high on a leg (about 5' off the floor). It has a short electrical cord that I disconnect when the hydraulics are not in use. Since it requires power to lift from the floor or to lift prior to unlocking the safety tabs for lowering, it would be difficult to imagine a small child activating the system. Older children would present another problem but I have a hunch the lift would be just another entry on a long list of potential disasters. In passive mode -- up or down -- everything is solidly mechanically connected and unbelievably heavy making it difficult for me to imagine a scenario where the system would become unstable.

Bill,

I have very young kids - I would agree with unplugging, so I suppose if everything is up and unplugged, chances of car slipping off is minimal?

That's a good thing!

I haven't read through all post but I have been satisfied with the four post I got (cheapest that I could find).

I did get the castors and extra jack pan. I had to be able to move it around and couldn't use a 2 post.

I use it on almost everything I've got (C3500 truck is too wide) including my Suburban. It is very stable.

Other points:

1. Being movable, I even moved it outside and lifted the Suburban to pressurewash the underside.

2. To change tires, brakes, etc..., lift a few feet, put jack stands under car frame, let lift down and then place second set of stands on ramps to car frame and then lift again. I usually work it up one end at the time but wind up all 4 wheels off the ground (and ramps) and the car with axles at eye level.

I know it sounds crazy but its easier than fooling with jacks and actually safer (more stable)

Who is the manufacturer? Always good to get another opinion/reference.

Found it on Ebay but talked to the people a couple of times on the phone. Been over 2 years but I think it was made in China. I think the same case with others mentioned with different prices for similar models. Several of the companies have economy models. This was what I could afford and it has been fine.
