Sonicare Elite 7500 Power Tooth Brush is one of the best products out there. I bought it a few days and so far I can tell you it does an excellent job on my teeth. The cool feature on this tooth brush is the automatic 2 minute timer. In the past I only brushed for 20 seconds and it wasnt effective. But now with this sophisticated Tooth brush I get a whole 2 minute brush in mouth and every 30 seconds it makes a beep which lets me know its time to brush another part of my teeths. Offcourse I do 4 minutes everytime because I just enjoy using my tooth brush. Crest Spin Brush can not compare with Sonicare. My teeth feel healther and whiter right now.
