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.
This unusual punch allows you to turn a dial-like knob to select three different corner punches. Cool idea. Mine cut nice clean corners with little fuss but only on paper and standard card stock (like most punches) -- in other words not tags or anything heavy. I'm fine with that. What I'm not so happy about are the different radius curves of the corners. The graphic exaggerates slightly because the difference between the three curves are not that great. I punched each in a different color of card stock and held them up next to each one. There is a difference but it is not that pronounced. I'm still keeping this punch but I would probably have researched other brands had I known I was not getting what is pictured.
The punch looks, feels, and operates like a high quality, ergonomic tool. It works great, and the only reason I didn't give it five stars is that it is too expensive. There are small punches that get the same job done for much less, but they feel cheaper in your hand - so it's a trade-off.
