[This review was collected as part of a promotion.] I give it a high 5 as I can feel the difference in cleaning my teeth. It lets me know if I am brushing too hard and makes sure that I Brush for 2 minutes, small beep when to change sides. This is awesome
[This review was collected as part of a promotion.] I had two previous toothbrushes with a white handle and base that plugged in. After a year or so, both died and would not recharge. Not sure why. Now this brush has a black handle and base. You no longer can plug it into a wall and instead need a USB port. Such is life in the 21st Century. I think the move has something to do with the environment. I am more interested to see if this one lasts any longer.
[This review was collected as part of a promotion.] I purchased my Philips toothbrush after trying Oral Bs. Philips was much more effective and easier on the gums.
[This review was collected as part of a promotion.] My new 4100 was great to take on a trip, very compact, 2 wk long battery charge after ea charge, slim and 30 sec timing beeps. Best brush I’ve ever had.
