[EX 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.
[EX A]: Bad review

[EX Q]: This should be more than an $18 speaker system. You will waste time and money.
[EX A]: Bad review

[EX Q]: this case did not fit at all had to return it. the colors are nice - kind of faded though so it looks very cheap. do NOT buy this. waste of money and time. also when i got mine a corner was broken off which didnt affect how well they hold my phone just gave me a sense that you get what you've paid for. i'd recommend spending your money on something else instead unless its completely flat like these cases are.
[EX A]:
