Review (4/5): Prefer the normal brush heads
I decided to try these new fangled brush heads just to see what they were all about... The center "paddle" seemed to be doing its job of directing water and toothpaste between my teeth, but it felt like it was a tad too long and hard, causing some discomfort on the gums. Maybe just something to get used to... However, comparing side by side the new heads and the old brush heads, I still prefer the feeling of the old ones.
