To any purse collector this book is invaluable for cataloguing and understanding their collection. I have referred to my copy so many times to help me with my collection! The photography is beautiful and the writing shows great knowledge of the subject. I have met Mrs. Haertig and she is an expert on purses having researched this book for over 7 years in many great museum collections in Europe and the USA. Her book is the standard for many museums with purse collections. The price may seem high, but to a collector of fine, quality purses valued in the thousands, the book is priced less than that of an inexpensive purse. Mrs. Haertig is an amazing lady in her 80s who is still writing books. Her latest book is "Restoring & Collecting Antique Beaded Purses" which has just been published after restoring hundreds of fine purses and giving workshops on purse restoration all over the country.

input:  Now, answer this question: Is this product review positive? Title: The best Bluetooth book yet, but... Review: I thought that this book started well. However, as the book moved on, more and more extraneous side material creeps into each chapter, while at the same time it becomes less and less detail oriented. The result is that more and more topics are introduced but not well explained. I would have greatly preferred if fewer side topics were discussed and more detail was focused on the central issues. I ended up spending the latter 2/3s of the book feeling glazed over. I still feel that this is the best Bluetooth book on the market, but that's because most of the other books are so terrible. No matter what book you buy, you will have to read the Bluetooth spec in its entirety. This book will at least give you a broad overview that the spec is so sorely missing, though that could have been done with far fewer pages. Answer:
A:
output: No

Unfortunately, the unit wasn't. Read the instructions but no matter what I did, the unit leaked out of the base and hardly any pressure was going to the handle. After a couple of tries, returned it the next day and got a WaterPik 70W Family unit.This WaterPik unit is really compact and easy to use. I've had it about a month now and it's worked great.I would've given the Homedics unit 1 star except it had a nice tip about keeping the tips clean by soaking them in denture cleaner. Answer:
