This a disappointing book.. No real plot at all. Slow and boring. Was this suppose to be some new twist on a true story? I have read every single novel Mr. Brown has written, however after reading this, it is definitely my last.
Bad review

I had some trouble figuring out where to find the batteries that came with it, so if you don't have a screwdriver (comes in small package of 4), think twice first about using it and ordering it right when you're leaving for vacation. You will need it at your vacation home.
Good Review

This little jewel is a joy to use, and cleans up just as easy - I am very impressed with the ease of cleaning it. Now on my second one, this one was so cheap that I gave it for Christmas... but not before making sure I would use all parts of it. Then after about three weeks, using every day or two, something happened inside. The white part (that covers where you put food in & take it out) kept coming out. So, now it's useless.
