Amazing customer service. I got an email after my purchase letting me know that it may take a bit to ship the order, which I appreciated. After I received it, I thought I thought I had an issue with it, so I emailed them and got a response right away. I really appreciated that. Since I just recently started to use it every night for 10 minutes, I can't say I have seen a drastic change, but I do feel like it is doing something. I will give it some time. For that price, it is worth it.
