These are actually pretty good

I am not one to cheap out on a toothbrush. I have an electric one that I use regularly, but oftentimes I will use a manual one, whether I am traveling or so be it. Anyways, so this toothbrush is pretty effective, allowing you to get a good thorough clean of your mouth. I like the rubber pieces within the bristles, it allows for a more precise clean too.
I am also a fan of the shorter bristles on the back of the brush that allows for you to brush you tongue. This toothbrush leaves me feeling satisfied.

What's the rubber bit about??

I bought a 12 pack of these toothbrushes without realizing that they have these rubber polishing caps hidden in the bristles. It makes it feel like it's not really cleaning my teeth, just rubbing them. I don't know what I'm going to do with a dozen of them.
