The Stud Finder
In early 2015, I had several instances where I needed a "stud finder" to install a couple of TV wall brackets and some "grab bars" in the bathroom and shower area. Dennis had a real nice Craftsman stud finder and I kept coming over to borrow it...a LOT. He told me that he thought I had used that stud finder more in 3 months than he had ever used it since owning it. He was happy that there was finally a use for it.
