I loved the pricing on this but I can see why it was the most inexpensive one. It was very uncomfortable to use. I ended up putting on one of my snow gloves each time I had to hole punch 2-3 papers at a time and that helped tremendously. Before i started doing that my fingers were starting to ache a little from the medal. If price isn't an issue I'd recommend getting the ones that provide comfort (usually $8+). I didn't want to splurge since it was a one-time project (so far!). Otherwise it did the job well.
Tried to punch multiple sheets at once. Did not just work but bent the entire tool to where the punch can not find its way into the hole anymore so that now I can not even use it.
