My wife has complained for years that I snore. I haven’t given it much thought as it hasn’t bothered me and I thought she was exaggerating. After 15 years she had had enough and moved into the spare bedroom. Couple of sleep studies later and a snore app on my phone confirmed I do in fact snore like a bear. A MAD from the dentist cost over 1300 euros so that wasn’t an option. So I tried the snorerx. It worked but the fit wasn’t secure and my lower jaw would fall out often. Next I tried the snoreowl. Fitting it I could tell immediately that it was going to be a better fit, not only did I fit my teeth but also onto the roof of my mouth and gums. No problems with it coming loose in the night. Like any MAD it takes some getting used to, but now I can sleep the whole night with it in comfortably. My score on snorelab is down to zero and my wife is moving back into the master bedroom. Highly recommend this product to combat snoring.
