When I received the Colgate SlimSoft Kit in the mail, I was super excited.I recieved my Colgate SlimSoft Kit from Influenster.com.On the packaging it stated that this brush has 17x slimmer tip bristles for a deeper clean.So I put it to the test.While brushing it felt like my teeth were getting a massage!This brush was very gentle on my teeth and I love how clean my teeth felt afterwards.This brush will definitely replace my old brush!
