I purchased this and was exited that there was one tool that would do three sizes of corner rounds. However, mine did not make a smooth cut, it left a tag at the end of the cut on all three sizes. I wrote Fiskars and they did send me one that works better but one side will still leave a slight tag. A little disappointed since I love this style of punch. Their customer service will send you a new product. I actually emailed them an example of the problem. I would recommend but with reservations.
I love Fiskars punches, the squeeze punch is so easy to hold and use, I now have beautiful neat corners on all my cards, what I love the most is you get 3 corners on this punch, so I do not have to waste money buying the different sizes I would need, it's all here in this one great punch, and the only one you will ever need. It's fantastic, and great value for money as well.
