Product Overview

I recently had the opportunity to try out the KRX Automatic Toothbrush, and I am truly impressed. This toothbrush is perfect for children, as it is designed to look like a toy and make brushing teeth a fun activity. The ultrasonic cleaning feature does an amazing job of reaching all areas in only 40 seconds, and it has a dentist grade LED blue light that helps to whiten teeth with every brush.

The U shaped toothbrush head is made of food grade silicone that is soft and gentle on delicate gums and sensitive teeth, plus an extra toothbrush head is included so you can trim it as needed. A great feature of this toothbrush is that it has USB charging capability, so you can easily charge it at home or while traveling. It only takes three hours to charge the battery, which will last up to one week.

In my opinion, this toothbrush is great for children who need a little motivation when it comes to brushing their teeth. The toy like design makes it much more appealing than regular toothbrushes which often puts them off from brushing their teeth altogether. The ultrasonic cleaning does a great job of getting into hard to reach areas, while the LED blue light helps to whiten teeth quickly and easily.

Overall, I highly recommend this product for anyone looking for an easy way to get kids interested in brushing their teeth on a regular basis. Not only does this toothbrush look like a toy but it also provides powerful cleaning action and helps to whiten teeth in less time than traditional brushes. Plus, with USB charging capability and long battery life, you don t have to worry about buying batteries all the time!
