My father and I purchased a HAPP 40 almost 2 years ago. We work as mechanics during the day for a dealership and use our Happ hoist of a night for our projects. We use Heshbon and Powerrex hoists all day, the Happ leaves them for dead! It has a wider spacing between the posts, allowing a door to be opened much further and the extensions for the pads are much more user friendly (not jamming in the arms like other brands.) If anyone ever brings up that they are interested in a hoist I can honestly say that bang for buck, HAPP leaves them for dead!
Thanks, Tim Murphy.
