I've had the bigger version (3 ton each stand) for about 8 years. Don't use it very often. It's good in design but have a negative feature. When raised, the jack won't lower itself after the load is removed. When you lower the car till all 4 tires touch the floor, you can't just slide the jack away because the jack is still tightly pushing against the car. You have to use your hand to push down on the jack fairly hard to lower it before you can slide it out. I use it primarily as a jack stand after I raise my car with a floor jack. I only bought 1 such jack (sold by piece, not pair), so usually use my regular jack stands (which are a pair) than using this bottle jack. Good design concept but not good in real life usage.
