I love all the eco credentials associated with this toothbrush. The colour is bright and I like that the handle and bristles are blue and don’t get mixed up with the other toothbrushes. The bristle are just right - not too hard or too soft. The reason I gave 4 stars is that I have a small mouth and the head part felt a bit bulky in my mouth compared to my previous bamboo brush. I’m sure it would be fine in most people’s mouths though. Maybe I need to get the child’s toothbrush!
