When I first got my jeep I picked up a knock off 'farm jack', it looked the same, felt heavy duty and was half the price. First time I tried to use it it didn't work, the smaller metal pins that go through the climbing pins were bent so in order to get it to lower I had to stick my fingers into the climbing mechanism, not something I was comfortable with. I figured I just got a lemon so I brought it back and got a new one, it lasted a couple of uses before the same thing happened. I returned it and finally got around to buying the hi-lift xtreme, those problems are gone and it works flawlessly. My only complaint is that it doesn't have some sort of cap on the end of the handle, it's just bare tube and it looks unfinished, doesn't affect the use at all and doesn't really matter.
