I finally got to play with my "Slice" today - for the first time! It's a sad affair when you have a new toy and can't find the time to play with it! I have 4 cartridges, but only played with the Christmas cartridge today. Here's a sample of the fun I had!!
It's very easy to use. Some reviewers don't like the fact that you have to hold it while it cuts. I personally enjoyed it and it doesn't take very long. I did notice that after using the blade about 6-7 times, the thicker paper did not cut as thoroughly as the thinner paper. Experience and use will determine how long a blade last.
