Prefer them to every other bamboo toothbrush from this brand and to any other kind of toothbrush.
As a newbie to the toothbrush sustainability, I tried to find a cheap and eco-friendly alternative to my mainstream toothbrush. That's why I chose the particular model. I've been always using medium toothbrushes, but this medium is kind of soft for me. I wish there were a harder version of it or the medium were actually a medium and not a soft. That's the only drawback I personally found and it cost one star from the review. If you prefer soft toothbrushes definitely go for it!
I ordered the soft one. It is andeed soft and the bristles are dense enough to clean properly. I have only purchased this once but I think I prefer this one over other ones I've used before and I am going to purchase it again.
Great feeling touch of the fibers (this material is ideal) and totally satisfying results.
