I was so excited to get this so I finally had something to use when I worked out, and to my surprise it sucked.. It wouldnt allow me to download anything to it, called the company for support and they had no ideal what they were even talking about. But I got my refund and it was easy to return.

These really work well for me. They make such a difference in the quality of sleep I get. Don't expect them to solve all your nighttime breathing problems (they aren't going to replace CPAP), but I they increase my breathing passageway about 30-40% which can make a big difference. I don't use them every night, just when I'm feeling stuffed up more than normal or when I want to make sure I get the best night's sleep possible (like the night before an interview or big test).
