Air Travel & Snoring

Hi All. I've been some reading the posts regarding using the CPAP machine on planes with battery pack and using a mouth piece. I'll be traveling on vacaction in a couple of months and my to and from flights are both overnighters. I don't see any need to purchase the battery pack for my machine for 2 flights so my interest is with the mouth piece.

I'm looking for opinions on how well they work and the best/most effective one available. I'm hoping that by purchasing one it will not only work effectively but will ease my concerns about snoring on a plane and disturbing all around me. I'm a low key person and the thought on anyone making loud comments regarding my snoring is causing me distress.
