All the reviews are from amazon vine voice. how can these be unbiased reviews? especially for something so expensive.

I am a Vine Voice reviewer and I still only gave it 3 stars. As a toothbrush it is great, and the carrying case is nice. But is it $200 BETTER than the model just below it? No, it is purely a "I am rich and want a rich person's toothbrush". Also, Vine Voices still have to pay taxes on the product received. In taxes this cost as much as the second best model, so Vine Voice folks are not going to get this and give it a highly rated review if they don't like it... at least I wouldn't.
