The Vevor air jack is a good product for the price. It is easy to construct and works well. The male coupling was not the correct one to fit my Nitto style air line, but the 10mm fitting was easy enough to replace. It works well with my compressor which has a maximum of 125psi. The extension handle joining bracket is not high quality, but will do the job. As long as the air bags last the distance I see it being a very useful tool. The 3t version I purchased lifts my average sized sedan in a few seconds which is far quicker and easier than the trolley jacks I have been usingto date. I would recommend this product to family and friends.
