Where to get GoSmile?

I’d read so much about GoSmile the teeth whitening product that you can use in the comfort of your home without having to visit people like Plano Cosmetic Dentists. I’d heard that it worked as did Crest strips.
I’d also heard that having teeth whitening done at the dentist can be painful
Especially if its by UV light. Scared me half to death. As if going to the dentist wasn’t already a traumatizing affair!
Anyway, I just saw that GoSmile is also available in Strawberrynet – a whitening and maintenance starter kit.
Dare I try it?
