   Awesome customer service. My toothbrush stopped working after like a year and a half. I reached out to Philips, provided proof, and got my replacement in less than 7 days. Amazing experience and will definitely buy another Philips product. In general, the product is very good. No dental issues so far!

   Es un equipo que cumple perfectamente con la finalidad para la que fue diseñado. El problema es que su precio es excesivo.

   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.

   So for years I’ve apparently been brushing too hard, and my dentist finally forced me into the electric toothbrush market.

   After doing some research it appears that Sonicare is legitimately better than Oral-B in plaque removal (around 15-20%) but is quite a bit more expensive on average. I tried the Oral-B option first and it was okay, but bothered my gums on the side of my mouth that I really brushed too hard on. The vibration isn’t really intense at all, and I actually enjoy it compared to the circular brushing pattern of the Oral-B. It also allows you to get more paste on the brush compared to Oral-B, which is a positive since I always felt like I was “running dry” with that brush.

   So now I’m using this brush and I think it’s fantastic, none of the sensitive spots I have in my mouth are triggered by it and I genuinely feel like I’ve just come back from a cleaning (in terms of cleanliness, not gum pain lol).

   So the toothbrush itself is nice, it’s easy to select modes and holds a charge for quite awhile. The main difference between this brush and the ‘dumb’ versions other than the app is that it actually has a pressure light at the base of the toothbrush. (Which I like)

   The app is decent, but not really worth the money in my opinion. It’s tracking tech works okay for the most part, but gets screwy if you move your head around, or look down at the phone. You can compare this to the Oral-B which actually requires you to hold your camera to watch you brush, and is even worse in quality.

   No brushes included. Suspect this was repackaged because the solid underarm deodorant is open and cap also missing. Wrong colour as per advertisement and no carry case as per advisement. Had to drive 60 min round trip to UPS to return. Disappointed!!!!

   I had a very old (like 10+ years old) Sonicare, which finally died so I needed to start looking for a new one. I decided on this, since it was app-connected and overall looked really nice, and it’s been fantastic! The app helps me make sure I’m not brushing too hard and that I’m focusing on all areas evenly, and the overall build quality and features make this toothbrush an easy recommend.

   I’ve been using this toothbrush for about two years, no complains! I like the travel box that I can easily bring it with me, and leave it in the luggage cuz the toothbrush actually last about a week(or even more, didn’t actually try the limit but it’s pretty long).
