Review (5/5): Great brush for the cost
The new brush is on the left, my old one on the right (note - NO MOLD). If you follow the instructions you won't get mold or growth. I figured that out way before they put the instructions out. Common sense is a good thing, I wish I could share that knowledge with people. If your worried about the bristles falling out check it out first before putting it in your mouth, give it a little tug. These brushes are so much better for our environment and if your looking at the product, than your trying to make a difference. And that is good! But don't expect things to be the same when your looking for something different.
It's not plastic, and that is the best part. Most of the items are bio-gradable and made with sustainable products. Far better than buying the bulk plastic. The new brush, by the same company, is a bit bigger than my last brush, but so far so good. I have no complaints. This toothbrush is great!
