Review on Klein Tools 53731: Optimized Adjustable Hole by Gavin Dunne

I bought this tool to install recessed lights in drywall. It's similar to the tool I used to install the lighting in our last house. This version was marked by failures. I tried cutting holes several times and each time the screws holding the cutters fell out, damaging the drywall and leaving bigger holes than I intended. After the first failure, I stopped tightening the bolts every few turns. In the end, this didn't work because the supplied hex wrench was a bit too small and the adjusting screws ripped off. I ended up buying a fixed size hole saw and was able to make perfect cuts with ease. Save money and buy fixed size hole saws.
