JMO. I bought a set of 7000's a few months ago when Home Depot had a special buy. They work ok. Takes a bit longer to get them setup compared to rolling a floor jack underneath. I also have 5 floor jacks. I have a set of magnetic pinch weld adapters on my daughters fusion which was on a set of the included rubber blocks. The rubber blocks has to be used because the pinch weld adapters do not hang below the rocker moldings. The right side rubber adapters kind of rolled while rotating the tires and bowed the rockier panel a bit when it contacted the jack. Probably my setup and the garage floor has a slight bow. Honestly they are a pain in the *** setting up because of the rise before the jack contacts the car.
As the jack lifts the lifting points on the jack move back, so you need to take that into consideration and also when the car goes up , it goes back.If you lift inside a closed garage make sure you are far enough forward for clearance.
They are also heavy, granted I purchased the 7000 series.I purchased the hangers to put them on the wall , but haven't hung them yet. they are heavy bastards, and im not too sure i want to keep lifting them up vertically for storage. The wheels that are on one end do not swivel, so lifting them on one end and shoving them around are not quite as easy as it looks. That also comes into play when setting them under the rockers.They have to be scooted and again its a lot of weight.
The other issue is the hoses. If your just lifting up for a quick maintenance, i wouldn't pop them off, so they get in the way.
Its a lot of setup basically, and unless your wanting all four off the ground a set of stands and floor jack would be quicker.I have a bad back and thought these would help, but the weight of them *****.
A 2 or 4 post would beats the hell out of these. I have both also,so maybe i am spoiled now, but they are at my other shop and I got these for a quick oil change and rotation in my for my 8ft garage.
I'm still torn on the purchase, especially when i go out in the garage and see them in the way when not being used. Its like my motorcycle table. Its great when the bike is up and on it, but its a big piece of furniture when its not.
