I’ve bought from Vevor before and have always been impressed, so my expectations were high when I bought this corner punch. The instructions were in crude English, but the quality of the machine more than makes up for this. I swapped the R6 cutter that comes attached for the included R10 cutter, and the level of adjustability you have is impressive. I’d recommend dedicating some time to setting the machine up correctly, but after that’s it’s set-and-forget, with a perfect and consistent cut every time.
