Example output: Cat hates them
Example explanation: It's a correct summary because the owner's cat hated the product.
Q: First, these do not cycle well from magazines in either pistols or rifles. They may even damage feed lips on mags. Therefore, these are worthless for a training aid. Second, they are brittle and have a limited life span. The only use for these would be for function testing since you can see a notch cut out in the cap after firing it so you can see if your firing pin is working.
A:
Do not cycle well from magazines, cheap-limited life span
