It's easy to snicker a bit at, but from what I can tell, it is just a matter of time until it happens to anyone that owns one. It has been my fear since I started using one about year ago to test reloads. I have a small star - like a windshield ding - in mine that I got on my second time out using it. Still trying to figure out how that happened.
It is a useful, fun, and somewhat expensive toy that needs to be bought with the understanding that it is probably disposable.
