I read the reviews before purchasing this product and was very reluctant to purchase it due to the problem with the jack. I took a shot at it anyway and was very pleasantly surprised! This jack pretty much was ready to use straight out of the box. I pulled it out, set up the tire racks and after driving the mower onto the racks; lifted the mower efficiently within 5 minutes. The problems others reported of the jack not working could have come from them not verifying the screw to release pressure and lower the jack was not tight. I confirmed it was tight prior to attempting to jack it up. Worked flawlessly for me. I also have experience with bottle jacks like this one and its not many things that will go bad with them. I truly love this product and it saved me tons of time changing blades and sharpening blades. I have two John Deere Mowers to work on and I replaced one set of blades and removed, sharpened and replaced the other with ease. The only reason I did not give a 5 star rating was longevity of the product. As time passes I will update as necessary. If you compared this product to other stores your going to pay hundreds more for equal lift value; or eighty dollars less for lower quality and lift value. So if you are looking for a reasonable priced product that works this is the jack for you!

The jack works good. Raised my mower to the height I needed and then secured the locking arms in place. When I went to lower the mower I raised it a few inches and released the locking arms. The mower started to lower and then stopped. I noticed both locking arms were slightly twisted and bent preventing the mower from being lowered down. I had to remove the locking arms to lower the mower. The locking arms were discarded. I use adjustable jack stands in the future once the unit I need to work on is raised up.
