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. As soon as the warranty expires, you could find yourself without a toothbrush. Given how much I paid, I thought I'd be using it for years, but it barely lasted through the warranty period. If I had purchased a more affordable toothbrush, I could have used it for years by simply changing the brush head. Additionally, mold can form on the toothbrush, which is quite concerning.
