[Q]: This product had no impact on our mouse problem,which was becoming less and less of a problem. We have been using this for over 3 months, maybe it has not done its job, but at any rate, we aren't convinced. The problem is, mice are attracted to the food in my kitchen. Mice cannot see through metal foil, so what works wonders for them would be useless here.
[A]: Bad review

[Q]: I have many types of knives, but this one is my favorite. The handle fits into your hand nicely, not too large or small. It has a very nice balance and feel. This makes a perfect gift as well. It's just so beautifully made. Would buy more from the company in future.
[A]: Good Review

[Q]: There were many grammar errors. While there are several typos in most books, they all had at least one error.
[A]:
