Labor Saving Arm - 440lbs Multifunctional Furniture Lifter Jacks, Lever Arm Lifter, Drywall Lift, Wall Tile Locator, Door Panel Lifting Cabinet Jack, Board Lifter, 15.5" (2PCS)

I'm not really sure what to say other than they work. I used them to jack a 250cc Honda Helix up for someone. The hand squeeze mechanism does feel a bit janky, but otherwise these work. They're alright quality, not like your grandpa's quality tools but they'll get a job done on a small engine.

This is the second pair of these that I have got and they are wonderful. I needed to lift a wooden cabinet a small amount to position and hold in place so I can screw in the fasteners. These arm jack tools lifted the exact amount to level the cabinet with the others. I even went higher to test out the incremental lowering function which worked great. It does have a quick drop button to lower all the way which is also quite useful.While I didn't have anything that was 440 lbs - max capacity - I did lift one side of my heavy couch which was quite easy squeezing the levers, I expected it to be more difficult. All in all, a great little tool which I will definitely use again and again and probably get a few sets.
