A comment
I came across a KPRH-1001 Meteor puncher on occasion. My Bosik got into repair, and during this time I borrowed a Meteor from my father-in-law. From the first sight it seemed a very decent device. In principle, he did not disappoint in the work, the power is good, he even coped with very hard material. I consider the fact that there is a power-on lock button a plus, although not a big one, and the presence of a case is important when you have to travel with it in transport.
But there are some nuances. As for me it is very difficult this time, and secondly, the lack of a dust bag upset me, I’m used to what I have, and I’ve swallowed dust. But in general, the punch is normal and if you take it for homework, then in principle it is possible. And for professional use, in my understanding, you can search for a more functional device.
