This is a great product. I purchased the butterfly punch. Very easy to use. I would suggest holding the base with the paper placed on top up to the light just so you're sure the base is straight. I highly recommend this product.
I was very disappointed in this product. It does not cut thicker items, such as Bazzill cardstock at all. It worked maybe 1 out of 4 times I tried and even then the edges were not crisp and the paper around it the punch was mangled. I tried using it in different positions and on different surfaces with no more success. It seemed to cut thin paper and tissue fine. Also the base fits on only one way and it can be frustrating to have to position and reposition repeatedly.
