Please pay attention to the reviews. I wish I had. I was skeptical and did read the reviews but also read a friend's review that was positive. What worried me were the customer service issues. I figured well if it does not work I can get a refund in 30 days. That's where a HUGE problem comes in. If you do try it (and I recommend you don't as they are glorified vitamins and caffeine and nothing more and the patches leave a horrible sticky film), make sure you refund well before the 30 days and document every little thing and get a tracking number, etc (shipping cost is your expense, too). They will acknowledge they received only if there is proof like this in their worthless customer "ticket" service but be prepared as you will have to bug them over and over and over and over again to actually get the money. It's unbelievable. Then when they do submit a refund they take out "restocking fees" and inform you it could take "14 business days" to appear in your bank. Hmmmm... I ended up having to do a chargeback. Several weeks later the refund is still not there. I read where this has happened to some other people recently, too. And no one will help you. You will get canned responses. No number to call. Nothing. Please think about this and just buy some good vitamins over the counter or something and save money and drama.
