question:
This machine is really good, but not without some problems. While the noise it makes does a lot to mask other noises, our cats definitely do enjoy this thing. It also helps keep them calm, which in turn, brings us much peace of mind. However, sometimes you need your hands free for something else -- like getting the cat out from between the mattresses.
answer:
Good Review

question:
It's hard to find a novel of this type and I was very disappointed. The prose is too good when compared against other authors who deal so much more with what it means to love someone. What does she love? He loves her. Can the truth ever be revealed? That depends on someone else. Who do we need to believe? This reader lost track of most of them.
answer:
Bad review

Don't waste your money on this piece of crap headset!! I had to return it two days later. The volume is really low and you can hardly hear what people are saying through the mic. This was also a defective set that I received. Amazon let me keep the one I had. Be warned before buying this!
answer:
Bad review
