Philips Sonicare DiamondClean Smart 9750 Rechargeable Electric Power Toothbrush Lunar Blue HX9954 56

Best toothbrush I’ve purchased to date. I had an old basic Sonicare tooth brush for over 7 years and while it still worked I decided it was time for a replacement. The app integration with the toothbrush is top notch. First time brushing with the new brush left my teeth feeling cleaner than my old brush would. The different power levels and modes are great if my teeth are being sensitive. The travel case will definitely come in handy for work and pleasure trips. Read more

The media could not be loaded. This was the first electric toothbrush I've owned and I've been really happy with it. It looks cool, it's comfortable, it works well, and it leaves your teeth feeling really clean. The battery lasts quite a while between charges. The longest I've gone without charging it was 8 days and it was still going strong. After three years and two months the wiggly bit went all floppy. I can hear something inside of it is loose when I shake it a little. Given the price, I was a little disappointed that it didn't last longer. I called customer support and they agreed to replace it once even though it was out of warranty. As long as the second one lasts just as long, I will feel like I've gotten my money's worth out of it and this thing will retain it's 5-star review from me. As for now, I am very happy with this purchase and would recommend it to anyone. Read more

The mechanism that transmits vibration to the brush head fails. The brush head rattles but does not vibrate effectively, making this no better than regular old toothbrush that costs $330. This is my second of this model. The first one lasted 3 years. The second lasted 3 months. I used Perplexity AI to search for customer complaints. Here it is: Common concerns reported by owners of the HX9954 model include moisture infiltration and seal deterioration, which can allow water to reach the internal electronics and battery contacts over time. This water exposure may lead to issues such as corrosion on the circuit board, lower-than-expected battery voltage, or complete device failure if not addressed promptly. Some users have also experienced a loose screw within the handle’s oscillator mechanism, causing excessive noise or vibrations until the screw is tightened again. Aside from these mechanical problems, some have noted battery-related issues, such as limited charging capacity or sudden drops in voltage, which can result from moisture reaching key components or from impacts that break solder connections on the battery terminals. If problems arise during the warranty period, replacement handles or upgraded models are sometimes offered, but customers have reported inconsistent experiences with manufacturer support or lengthy claims processes.
