They promote their product with a guarantee that you will see results or they will refund you the purchase price. However, in the terms and conditions they will only refund the product if it is unopened. How is that a guarantee? They will also make you pay shipping and stocking fee for returns. I tried to cancel within 24 hours and they refused to cancel and told me to ship it back. Well I may as well keep the crap or be stuck paying $17 for a product I did not even use. I highly recommend staying away from ordering through this company they are very deceitful.
