I bought SDI half year ago.
In the past half year, whenever I saw a dentist, I ask their opinions about SDI products.
I asked 3 dentists and 1 specialist, all dentists were using SDI products, the specialist said he didn't use SDI product, but they all said SDI whitening products are good.

I asked one of the dentist: since you are using SDI Products everyday, why don't you buy some shares?

He said he never thought about it, maybe he should buy some.

I will ask him again when I see him next time.
