I have used several different products the past 5 years year, and most recently SnoreRx. It has been about 2 weeks with the vitalsleep appliance, and can see it is a superior product to what I have I have used in the past. SnoreRx use to be similar in quality but they made changes to their product and the durability just isn't the same. So far I have been getting great sleeps, which doesn't happen if the "chain saw" is able to start -up. They just need to find a way to keep my mouth shut so the appliance doesn't fall out.
