I personally love these shears and have bought many in my 30 years working with metal roofing. If you know how to use scissors, you'll enjoy using them to make clean, quick cuts.
I was doing some work on the 26 gauge latch duct in my house and was struggling to cut it properly. These snippets fixed everything. Very easy to use and cuts great. What more do you want? That's what the pros use, that's what you should use too.
These things cut sheet metal really well. ADVANTAGES: - Really effective at cutting sheet metal (and plastic if needed) - Made from durable material. Doesn't feel or appear fragile. CONS: - Requires two hands to complete the cut. - Can sometimes pinch fingers if not careful.
