I'm a tool guy, and I never knew these things existed until now. The ability to punch a clean 2-1/2" hole in sheet metal, without involving rotating blades and metal shavings, gives me a warm fuzzy feeling. And this thing does a great job. I've only used it to punch four holes, so I can't yet comment on its longevity, but I see no reason why it wouldn't hold up pretty well if used and maintained carefully.Be aware that you will need a punch driver kit (e.g. https://www.amazon.com/dp/B0B5JMKV3V) in order to actually use this product.
