When I got the punp there was damage to the top cover and moenting base. The unit worked fine and Vevor sent me the parts to fix it. Very happy with my purchase. I use it on a Bendpak Ranger Motorcycle, 4 wheeler, and Lawn mower lift. I was skeptical about my mower as the lift was only rated for 1,500lbs and the mower was 1,600. Lift works perfectly with the Vevor pump and shows 6,000 lb PSI getting the mower to rise !!
