Yes! Its worth the $$ and Yes! it performs!
I was using a cheaper  model rotary style brush for the previous 2 years when it finally broke. They used a thin metal that reached all the way up into the brush. It rusted and snapped. I pulled it apart and found it was about as thick as a the metal in a small paperclip. Braun uses a much thicker metal stem system that does not go all the way up to the brush, but rather the brush is made to reach down to the stem. Much better build quality. Much easier to dry off if you want to and being at least 3 times thicker it will last for years compared to the other brush.<br />When I researched the heck out of Electric brushes, I found the Braun 3D Excel was #1. Yes, it topped the famous sonicare. Sonicare does a better job advertising while I spent less $$ and have a better product doing what it should be doing. Cleaning my teeth. I do tell people about this product. Its something that actually lives up to its repuation. Its one of the great products in my opinion. After about a week of using mine, I ordered another and had it sent to my mom.<br />When I first turned it on, I was impressed already. I could tell it was high quality. Then I began using everyday and have done so for over 1 month now. I love the timer and try to brush 2x a day as recommended. Its great and my teeth have improved. I can tell they are smoother and whiter and feel much better. I can feel that my gums and teeth have tightened a little better where I used to feel bigger gaps when flossing. I will never go back to using a stick brush and I can only imagine how impressive the next generation of electric toothbrushes will be. Awesome already and if they improve on this, it will be amazing.  If youre too cheap for Amazon, they can be found on ebay too. Its worth the money especially when it keeps the dentist away. I rate this product 5 huge STARS. Get it and you wont regret it.
