I finally got around to using this hydraulic jack. It is the first one I have owned and I regret waiting so long to get one. This is a solid jack with a solid base. The piston movement is very smooth and the jacking motion makes lifting my car effortless. So far, I have been very happy with its performance.

First the jacks - I bought two, and used them for a little, while leveling the beams in my house. Upon receiving the jacks, first thing I did was to check the oil level. Both were a little low, so I added jack oil as specified. After using them, one jack started leaking oil, and the other's shaft bent a little so scrape marks were visible on the side and it would not move smoothly. OK, at this point, I figured they were pretty cheap, but was not really outraged ... yet. So then I went to the local Sears yesterday to do a warranty exchange. These have a ONE YEAR full warranty. Sounds good, but it turns out what actually happens is the store will refuse to do anything at all, saying they are only authorized to process returns within 30 days (I was between 30 days and one year), or process warranties for some lifetime products (hand tools, primarily) and extended warranties. So they tell me to call Craftsman Warranty Service, and give me the phone # for them, and I make them call them for me, at the register. AN HOUR AND A HALF later, after dealing with the most incompetent people on the planet (for example, a supervisor who did not have a grasp of the concept of numerical measurement such as one year and relational concepts such as greater than / less than - seriously). So I was denied in store, dealing with incompetence over the phone. Basically denied on all fronts, screwed. Nobody cared at all. After an hour or so, the call got dropped on one of the many handoffs. Calling back in, I stumbled on someone with a reasonable understanding of things, who understood how things should work and understood the situation this decrepit corporation was in. He ended up getting into an argument on the phone with the store manager. He apologized to me for the manager's rude behavior and ended up just giving me SYW points to account for the price. So the lesson is - DO NOT consider the warranty to be worth anything at all. You have 30 days to return it. After that, you are on your own. And do expect to add some oil when it arrives. I'll never go to that store again (Fairfield, CA), but probably will continue to buy Craftsman tools. When I do so, I will value the lifetime warranty, but consider any other warranty to be worthless.
