All but 3 flavors were nasty!! The only good part about these are the fact they do NOT contain any artificial sweetens. But other than that, it's gross.

Bad review

No where in this product description does it say &#34;FOR THE Kindle Fire HD!!!,so now I have a useless piece of metal that will probably cost more to send back than it's worth. If I knew I had a new generation and didn't own the one for my older kindle, I'd get my money back. I'll still use Amazon's great service, but not THIS product. They should advertise these items properly. This was NOT made correctly.

Ex Output:
Bad review

My son really enjoys it. it came in a very nice carton as well. It is easy for him to use and his parents are quite pleased with the purchase. I would not hesitate or recommend this product. Also, they received it promptly within three days. Thank you so much! We look forward to buying more from you.

Good Review
