Read the detail comments  -most are paid reviews for this product.
Since there are so many fake paid reviews (yes heavily discounted or free is paid) I thought I'll try to put in a review on behalf of the paying customer. In summary this product seems to have great reviews but If a paying customer does not read their reviews buys by just looking at the overall ratings they will miss the fact that most reviews are paid reviews. Amazon needs to stop this from misleading customers but until they do I'll do what I can to try to help be a voice of the consumer
