Sleepon M2 Anti-snoring device is JUNK.
Anti-snoring device is not made for a human being, doesn't come close to fitting. I have bought them before at drug stores and they fit perfectly. The product page has no warning about this, nor how they deal with it, which is to offer half a refund. This is ridiculous given the high price of this piece of junk. Stay away from this unethical company. BTW, my mouth and teeth are average in shape and symmetry. Shameful.
