Review on Efficient and Powerful: Pro-LifT B-033NC Grey Hydraulic Bottle Jack - 30 Ton Capacity by Choice Maynard

I like how the jack can be lifted from the top and carried. This makes it easier to attach. I don't like that the piston only goes up about 7 inches and doesn't have a center piece that can be screwed in to increase the amount the jack can go up. I will say they are heavy jacks and you can tell how much they weigh. They weigh about 30 pounds each.
