I bought this after reviewing several others. It went together pretty easy although their are no instructions. Other reviews described problems installing the pump lever. I used a carpenter adjustable wood clamp. It fit between the pedal arms to compress the pump return spring and made an easy install. After using it several times I think its a good investment for light duty use in my home shop. I would be concerned to lift anything at its rated 1,100 lb listing. I'm just not sure its heavy enough based on my 45 years as a mechanic.
