This weekend, I fell in love with it all over again. While I've already experienced the time savings when you need to do maintenances on like 10 rooftop units, this was the first time I used it in a higher torque application.. Needed to drive 50-odd tapcons 1/4 x 1 3/4 into concrete and brick to repair some wind damage and as a preventative measure on other fake shutters on a property that I'm maintaining. I didn't even feel the effort as that little thing was doing its work without complaining and the battery was already a little stale from 2 weeks of use on the job. Compare that to the Ridgid 18V regular cordless drill that I used to drive 10-15 tapcons while fastening a shed foundation - needed to break out my socket set to finish the job. Of course, if you do a lot of install work, you want an 18V impact driver, but this little puppy will do in a pinch.
Consider getting the PS-41 instead for a few more bucks as it's a lot shorter for tight quarters work (main benefit), has better batteries (for you refrigeration guys) and even more torque (not that I needed it in this application lol).
