content: Tio was the name of a pretty neat modular toothbrush on KS. It is made in two pieces, so you just swap out the heads but keep the body. It cuts down on plastic waste and I thought it was a genius product. Happily funded it. Sure it took maybe 5 months to get what I paid for, but they delivered on their promise and it's a pretty good brush. I also funded this tea-infuser but that was over eight months ago. Still no word on when I will receive it, but it was a more complicated product that a plastic brush.
