I bought Phillips Sonicare flex after watching the ad on tv .I have been  looking for a replacement of my Sonicare elite toothbrush, used previously. I bought this product after searching on the internet and vaious other stores like walgreens, CVS and walmart for the best price. I finally found it at walgreens on sale and also a $10.00 coupon to use with it. I brought it home, put it in the charger base and next morning I was delighted by its performance. I used the quick mode, then the complete care mode which lasts 3 minutes. then I  used the sensitive mode and it massaged my gums so softly....
