William
"I don’t use it for only two hours; I leave it on during the night... I always wake up smiling… it is working really well...! Not too expensive either!"
Anna
"It worked really well, I have always had stained teeth if not very yellow. But now they are evenly white and I get positive comments daily! But of course I am not revealing my secret;)"
Tess
"Seriously, it really works. For real! I'm really happy. Have somewhat crooked and lopsided teeth so I thought it would be difficult to get it even, but no it worked great =) THANK YOU"
