I honestly wasn’t expecting this jack to work very well considering where it’s made and its price point, but I needed a jack capable of lifting a lot of weight in a very tight space. This little jack turned out to be perfectly on point. It is able to lift the entire rear end of my 4x4 suburban by the differential quickly and effortlessly using a tiny little 10 gallon compressor like it weighs nothing. I had to add some wood blocks for height, but it didn’t bind or hop going up or down, and even though the lift plate seemed wobbly and dangerous at first, it didn’t affect its stability once a load was applied to it. It goes up and down evenly and safely. I’m truly impressed with how well this jack works. The controls are simple and the jack is more controllable than a long handled hydraulic unit. Don’t get me wrong, you can certainly tell this thing is made overseas, and I’m sure there are far better built systems available, but not in this thing’s price range. For what it costs, and what its capable of doing, it’s a pretty solid tool. Like anything else, use it for what it’s designed for and be careful. Take the time to be safe and aware of what you’re doing and you won’t regret buying one.
