9900 Prestige Rechargeable Electric Toothbrush with SenseIQ, Midnight HX9990/12

I have been using it for nearly 3 months, I like it and the battery holds charge for around 2 weeks with regular usage, the travel case is neat and slick. It is definitly pricey but it gives me a good battery life and cleans the teeth well.

Muy buena calidad y fácil sincronización con la app. El uso es muy sencillo e intuitivo. La limpieza es profunda y desde el primer uso se nota la diferencia con otros cepillos. Lo recomiendo sin dudarlo.

The moment you use it, you will see and feel the difference and cannot go back to the regular brush.

I am extremely disappointed with the Philips Sonicare 9900 Prestige Rechargeable Electric Power Toothbrush with SenseIQ. Shortly after purchasing this toothbrush, I encountered a significant issue. When I changed the brush head, something inside the device became loose, causing it to malfunction. Despite my repeated attempts to seek assistance from Amazon, I have not received any help in getting the toothbrush repaired or replaced. This has been an incredibly frustrating experience, and I am left with a defective product that I cannot use. Given the high price point of this toothbrush, I expected much better quality and customer service. Unfortunately, this experience has left me thoroughly dissatisfied with both Philips and Amazon. I do not recommend this product to anyone looking for a reliable and durable electric toothbrush.
