Review (3/5): Decent for $20
I bought this approximately one year ago when it was only $16.99. It worked well... much better than regular (manual?) toothbrushes and my dentist noticed a difference. I like that it signals after 2 minutes of brushing time since I tend to not brush long enough otherwise. Maybe that's why my dentist noticed a difference.
The toothbrush broke after about 9 months of use. No biggie for a toothbrush that was less than $20. However, as I am writing this review the toothbrush is selling for $40, which makes it not worth it anymore. I have since upgraded to the "Oral-B 1000 Professional Care 1000 Electric Toothbrush" which I also ordered from Amazon. It's priced at $48 and I would definitely recommend spending that extra $8. The "Oral-B 1000 Professional Care 1000 Electric Toothbrush" feels like it has more rotations per minute, and just feels much better in general. I am going to assume that it will last me more than 9 months as well.
