[EX Q]: Didnt work at all. As soon as I began filling a tube it would shut off (overheating). Wasnt happy as I hade 7 tubes to blow up. Luckily I had a manual one.
[EX A]: negative

[EX Q]: Literally not the same bag. No pocket for credit cards and keys, no side pockets for umbrella/water bottles. No mesh inside pocket. It's the same shape and color that I ordered with none of the features. So annoying, I ordered this bag to hold specific items during a flight TOMORROW, and now I have to rethink my options. Thanks for the quality control, Amazon.
[EX A]: negative

[EX Q]: Before buying this book I read a ton of these reviews and was actually concerned that I might also be too set in my ways to be able to learn and grow from reading it. Thank goodness I'm not, but that in no way means I'm cured. As the book basically says, it takes a constant life-long effort to not contribute to the race problem in the US. The book is very thorough about setting expectations and about defining racism, bigotry, prejudice, etc. The vast majority of the negative reviews and complaints about the book are from people who somehow misunderstood what the book is about or who somehow missed reading the thorough definitions and expectation-setting in the book. I definitely think this book is worth reading.
[EX A]:
positive
