Query: Time Saver!!

I have been using this to hang drywall and HardiPanel on my home's lower level. It takes about a minute to screw down a sheet once it is in place. When I think of time I would have spent nailing or using a non-collated gun, this tool is worth it. Even on the small job I used it for, it saved me at least an hour of time. I will update this review after rebuilding my lower deck.
