Punch gets stuck
When any of the crop a dile tools work, they are fantastic. Unfortunately, this tool tends to get stuck. The punched pieces are stored in the tool until it is emptied. These punch pieces seem to get stuck in the mechanics of the punch and will not allow the punch to work. I seem to be using more time trying to shake the punched pieces loose so that it can be emptied, rather than using the punch for it's intended purpose. I would rather have the mess of having the pieces fall out rather than stored within the tool.
Another design weakness is the silicone cover on the handles are always sliding out of position on the handles. Just a little irritating.
Other than the two design flaws, the tool is still better at punching through materials than any other tool I have come across. Would still recommend it to friends, but I would certainly warn them of the shortcomings of the product.
