[EX Q]: This was an exciting book. It was hard to put down and I read it in a day. The suspense was palpable. Awaiting anxiously for the next book in the series.
[EX A]: positive

[EX Q]: I ordered the Hot Chow Chow and received the mild Chow Chow two days late. This is a non-returnable item so I'm stuck with it. I can buy mild anywhere. The Hot is hard to find. Disappointed with this supplier.
[EX A]: negative

[EX Q]: Ordered 2, one didn't work or charge. The other charged but the light never turned green showing it was charged. Hard to believe this is 3200 lumens. Not happy with purchase.
[EX A]:
negative
