Impossible to mold, doesn't stay in place, tough to breathe:(
The molding process is an impossible joke.  You're instructed to position the guard on the tines of a fork.  I tried several different forks, and all my guard did was float off and swim around in the hot water.  It was a molten lump of plastic each time, and I couldn't even get the slot for my teeth to open up.  After four attempts, I got it properly molded up and onto my gums.  No matter how thin it's pressed above my teeth/over my gums/onto my soft palette, it's still very easily removed and hasn't stayed in for more than an hour.<br /><br />Also, I hope you don't have any need to breathe through your mouth at all, because you won't be able to with this mouthguard in.  I have slight allergies and maybe 1 out of every 5 breaths happens through my mouth instead of my nose.  This mouthguard is so obstructive to any mouth breathing tendencies you may have, it's actually caused me to panic and wake up because it's slipped out of place and completely blocked my mouth.  I'll probably be lucky if I don't choke on it.  It does stay in place for the most part, but one touch of the tongue or wiggle of the lips dislodges it, and no amount of re-molding has fixed that.  I've had dentist-made appliances that have stayed put, and boxing mouthguards (for fighting) that have stayed suctioned on to an unpleasant degree, so I think it's the device, rather than some unique feature of my teeth (I've got very normal, straight, rather perfect looking teeth, and an otherwise unremarkable mouth and gum situation).  This product just took my money when I was desperate for help.  Well, I'm still desperate, but my wallet is a little lighter.
