11 ton model. Although I haven't used it anywhere near its rating, it has worked flawlessly. The plunger is hard to press on, so removing something underneath can be a little painful. I like that it can be used horizontally. When working on my 4X4 pickup, I didn't have to put blocks under the jack to get the truck high enough. I did have a lot of blocks laying around, but if repairs needed to be made in the outback, lifting the truck might be high enough and might not be safe. The valve works great! Not only does it drop a load out of a small turn, it easily adjusts speed to suit your preferences. Lots of power in a small body, large piston, screw fit for even more flexibility, fairly easy to use and very versatile thanks to the side mount option. The best bottle jack I've ever had. Update: I have a stump centered golf cart. No matter how I tried to swing it, put firewood under the wheels, or pull it out with a lever, it got stuck. Jack saved the day. He was able to lift the golf cart high enough for me to put blocks under the wheels and drive away. It also helped me install a new seat in my truck. My old one is very worn, so I'll buy a good used one. It turned out to be a little pinched and I couldn't line up the holes no matter how hard I poked and pushed on it. Then I laid the jack on its side behind him and that made the job easier. Most jacks can't do what they made. This is an excellent jack. Now, after a while of use, it's easier to lower the plunger back down.
