What a difference!! I haven't used an electric toothbrush in over 10 years because I assumed my gums were too sensitive. I bought the double set yesterday for myself and my husband and brushed as soon as I got home, even brushed thru three timers! I chose this brush over the sonic because I wanted the small round brush head - it made brushing behind my teeth so easy and I could feel the flossing bristles working give a great deep clean. The timer is another feature that is good because I will have so much on my mind when I'm brushing. I'm going to recommend this toothbrush to everyone I know, considering how well it works, how clean my mouth was without hurting my gums, and the price is a fraction of the sonic!
