Oral-B iO 6 Toothbrush Broke After Warranty and Mold Formed on It
The adhesive on the shaft of the Oral-B iO 6 toothbrush gradually loosens over time, rendering the toothbrush unusable. ...I expected a high-end product to be durable, but unfortunately, that wasn't the case. It feels like a classic case of planned obsolescence and certainly doesn't justify its price.
