I purchased this book as we are currently on a trip to Rome. It is beautiful and well written.
Good Review

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.
Good Review

When we first got it, there wasn't any information about what kind of adapter to get -- just that you can't use ordinary batteries since there's not enough power.
