Horrible design, mouth sores!
Hands down the worst heap of crap i have ever purchased on Amazon and this is saying something.<br />Mouthpiece WAY too small.  It is hard plastic.  Not soft, not pliable.  Maybe this is a childs version?  I spent some time soaking in hot water and opening up the curve of the mouthpiece extensively to where i could simply close my teeth on it although the fit was still far from acceptable.<br />Once i was able to use it, I found that the power source is a nuisance to switch on.<br />Why have an external battery hanging off a cord?  What if somebody wants to use it while sitting in a bath?  The battery is prone to getting submerged.  Make the battery and mouthpiece all self-contained like some other brands.<br />Now, even worse than the ridiculous fit of the mouthpiece, the damn sores in my mouth!  Ulcers on the insides of my lips after one use.  ULCERS!!<br />Do not buy this product.  Mine is going straight in the garbage.
