Question: Nice book, the only thing I didn't like about it was that each time a new topic came up throughout the first 30 pages or so we learned more than needed and it wasn't very interesting. It also gets a little boring around page 100 but does pick up. If you think you're going to take pictures of every bird in a local neighborhood, buy several books on your own first, this book is an okay one for that.

Answer: Good Review

Question: This item takes 8 hours to charge, so for the price I did not think it was worth it. When you are ready to use it, it's already half charged. So then your phone is dead. It does hold a charge well though but when you spend that kind of money, you'd expect more. The charger would be much better if there were some way to tell where and how long its charging for. At least it has blue lights. Overall, not impressed.

Answer: Bad review

Question: I love the idea of what this product could do. The technology is great. Just wish it did not stop working. Got about 4 uses before one day it would not even power on. Customer service said they didn't see any other reviews in the return portion either. When a device was defective and you cannot get to customer service, that tells me there are some bad apples out there. For a price like this, I'd expect better. This will be returned. I'll go with Apple next. I sure did.
