I am a 23 year old engineer / investor / web designer - and I had bad teeth (I have pictures to prove it!) I found out that for a small 17% premium in price, I could get Invisalign - invisible braces!!!!
Too good to be true? - no. I have had my invisalign aligners for 12 weeks and LOVE them. This technology enables someone like me - a industry professional, to have braces and nobody has a clue.
My experience alone pushed me to buy this stock, and while it has gone down from where I purchased it, I am still happy and confident that the company will continue to grow and market this wonderful technology.
I think that 10 years from now - Invisalign will be the primary orthadontic appliance used to straighten teeth. - People are very concerned with looks. I can't imagine having the metal stuff showing on my teeth while trying to meet with clients.
GO ALGN!
