Philips Sonicare ProtectiveClean (2017) vs Philips Sonicare 2 Series (2014)
Philips Sonicare ProtectiveClean 6100

The Philips Sonicare ProtectiveClean 6100 is a great Electric Toothbrush for its $97 asking price.
The Philips Sonicare 2 Series, however, while a reasonable product for $39, doesn't stack up against its competitors quite as well. If you're considering Electric Toothbrushes in the $30 range, you might want to check out some better options.

We conducted an analysis of all of the review data that we could find on these two products. First, we focused on sources that tested and rated both of them, like TechGearLab, and learned that they all showed a preference for the Philips Sonicare 2 Series.

Due to the difference in their prices, however, it's important to keep in mind that a direct Philips Sonicare ProtectiveClean 6100 vs. Philips Sonicare 2 Series comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
