Bamboo Sonic Replacement Heads - 2 Pack

Excellent

I'm rating this as poor because the replacement package toothbrush heads don't fit completely into my toothbrush handle. They are a smaller size and have a round hole. I can't use them in my sonic toothbrush.

Works okay

Heads work okay, some bristles come out with use and need to be plucked out. I was disappointed that my refill order was mailed in a plastic envelope. I think most people are switching to bamboo products to reduce plastic use.
