I like that the slot punch is light weight and easy to handle. I have small hands.
It does take a few practice punch to line up the next one but the "window" underneath helps. I wish they came in larger sizes.
The size was misprinted in the order area. So what I thought I ordered did not arrive, I received a smaller one. Contacted the customer service right away and they resolved the problem on the spot. They didn't leave me hanging or give me a hard time. Quick, courteous, professional service. Thanks!
The product itself works great. It may not be intended to punch thru plastic which is my project's medium...and it leaves some "hanging chads" :) sometimes. For the most part it's a clean punch.
