Works well. I made many holes already.

So far this works great. Tried it on a synthetic belt and it worked like a charm. I had previously tried to create this hole in this belt with a kitchen knife, because we were in a hurry to leave and the belt didn’t fit, so the edges of the hole are a little bit messy because of that, not because of the tool itself. Will try it from a fresh part of the belt next. Each of the hole punchers on the tool has a taper at the very end, making them very sharp; so when you apply pressure to the belt, the sharp edges cut easily through the belt material where you are trying to make the hole. You have to wiggle it a little bit and apply some pressure, but I am 30 and mildly-our-of-shape and I could do it myself. Would recommend.

It's very good

Is not the sharpest and doesn't do a smooth cut even with the thin belts. I don't think this will work fine with thick belts
