I bought this toothbrush today. It is a Trisa brand toothbrush with that comes with two sets of bristles. The bristle heads snap on securely. I had to apply quite a bit of force to remove the head from the handle. I have twin daughters that are 15 years old. They could not get the head off the toothbrush. Asking someone stronger than you to change the head on your toothbrush after you have been using it for three months sounds kind of intimate.
The intended end user of the toothbrush gave it a thumbs up.
From a plastic reduction standpoint, the Trisa my Planet is okay. There is a precise comparison on the back panel of the package. Compared to buying two toothbrushes, the my Planet amounts to an 81% reduction in packaging and a 70% reduction in the materials used for the product. The overall reduction in materials is 72%.
I wish the company had gone the extra mile and used an alternative packaging strategy. I also wish they had included more than two sets of bristles. The store did not have any replacement heads. I do not know if the company even packages them separately. I wrote about other options last year, but I haven’t seen any of them in local stores. If the my Planet and the Preserve were side by side on the supermarket shelf, I would have a hard time deciding.
EDIT: The toothbrush that I bought was for my son. I am seriously considering giving miswak a try when my toothbrush wears out.
