This is my second Sonicare. My first one lasted at LEAST 10 years and finally wore out. The secret is to fully charge it, then don't charge it until the battery light beeps and flashes at you. It will last a very long time!

I am so glad to reunite with this toothbrush. I had tried an off brand and a more expesive one. Neither of them made my teeth feel "clean". I also like that there are 2. One for everyday use and one for our permanent camper.

Great tool, does a great job. Really like the feel of my teeth after every cleaning. Especially impressed with the amount and regularity it gets food out from between teeth and under gum line, eve after flossing.

I love choosing between a 2-minute clean and a 3-minute clean. It's also great to brush the front and back of my teeth. This is my second Phillips electric toothbrush, and I am delighted with its performance.

Ever since I started using Phillips products, I have been very satisfied with the product and the customer service and I recommend your products all the time. I have great confidence in Phillips products .

My 1st one was making a loud sound, the top was loose and I have to use the warranty for a replacement. After 2 weeks came the replacement until now looks right crossing my fingers the tip keeps okay and won't make loud sounds.

The Philips Sonicare ProtectiveClean 4500 give much better results than a conventional brush. The 2-minute timer and the UV sanitizer is considered particular useful.

Sonicare I have been a Sonicare customer for over 10 years and this is the best model. Battery cycle time is excellent, the ergonomic design is easy to hold and comfortable to use.

after 2.5 years it died and wouldn't turn on anymore. It keeps happening to all the phillips toothbrushes I buy. I don't know if it's worth it. The brush heads are also very expensive. Going back to old school toothbrush now.

Great valvue.
