Review (2/5): good brush while it lasted
Yes Sonicare is the market leader. However, their quality control is slipping. I purchased this toothbrush in Sept 2010. By January 2011 it would no longer hold a charge. Past the product return window. I did buy another Sonicare, but I'm also posting this review for others to be aware. They will replace the handle, but only 28 days from purchase for cash return.
