I purchased the jack the other day with the intentions of using it periodically during oil changes and tire rotations (I'd love a nice floor jack, but can't afford it at the moment [ie my wife says I can't buy one right now]). I had originally wanted a 4-ton model, but for some reason Sears is discontinuing it and, thus, the store did not have any. This 2-ton model is plenty for my needs right now and the price was right so I got it. When I got it out of its box I was amazed at how tiny it was. I thought there was no way it could lift 2-tons. I stuck it under the frame of my Nissan Frontier Desert Runner and sure enough it picked it up without a fuss. It didn't pick it up much, though, because it's so small, and the frame of the truck is pretty high off the ground (it would have no problem on a car). However, two short pieces of 2x6 under the base gave it more than enough height to pick the tire up off the ground. It's a small price to pay for something as portable and useful as it is. It is as at home in the garage as it is the trunk of a car.
I bought this jack at a local store a few years ago and I used it a few times on my Civic. It clearly has more lifting ability than I need for my small car. It does have a small diameter contact area which is a problem. The main issue is that the metal is highly sensitive to water! I had it in the bottom of my trunk for some time with a bit of standing water in there. There was significant rust but it had not seized and I cleaned it up, dried it up. Put it in a zip lock bag on my shelf because I no longer trusted it (and I found my OEM car jack). A while later, maybe a year, I come back and dig it out while doing some spring cleaning and it's RUSTED again! this time it is seized. Rust everywhere. Think titanic after 20 years or so. The bottom of my trunk? No rust. The metal in this jack does not resist rust (no Zinc, etc). I would not recommend it in any sort of region where it rains at all.
I bought one of these to toss in the trunk of my car to replace the worthless jack that came standard. I've used this jack since to help others, and it performed flawlessly. Worth every penny!
I like the jack. Easy to learn how to use and easy to use.
The one thing that was not great though were the cashiers there inside the store. The guy at the pick up area was great....went and got me the jack quickly and politely. But the 2 young men at the registers inside the store wanted to do anything OTHER than their job. They carried on a conversation with each other the whole time he was ringing me up. It was like I was bothering him/them!! Their customer service was..........nonexistent.
