Review on Malco GOP23UK Standard Rectangular 2X3 Inch by Pushkraj Love

I bought a gutter release tool and a 2x3 rectangular punch. The punch came without mounting screws because it was used and returned so I had to contact Malco to get the correct screws as I couldn't find exact fitting screws at the hardware store. My biggest complaint is that the 2x3 hole is too small to fit in any 2x3 exhaust funnel I can find. I hate round holes! They are the easiest way but not the right way because they are too small and restrict the flow too much and the sheet metal screws used on them restrict the flow even more and trap more dirt and if you use anti-icing cables, round holes are basically useless and get clogged all the time. I've found more problems with the round funnel than any other. I like oval funnel drops but I can't find an oval stamp.
