This is the first high end electric toothbrush I have ever owned so not much to compare against. However, after a few uses I can already tell that this is a far superior method of keeping teeth clean and healthy and I am extremely satisfied. Actually, I'm excited to learn more about it and reap the benefits! There were some negative reviews about the single on/off and settings adjust button but it is easy to use once you get the hang of it. If you turn on and then hit the button again within 5 sec it will go into adjust modes. No biggie, just don't be a happy button pusher and you will be turning it on/off first try. Also, the quality of the product from the chargers to the brush and heads themselves are impressive. Really liking this purchase.
