I purchased this Oral B Professional Care 1000 toothbrush to replace one that had ceased operating after three+ years of use (full life unknown as it was a hand-me-down before my three years of usage). I prefer the narrow body of this toothbrush, takes little countertop space, and it does a good job cleaning. The battery maintained it's charge holding capacity throughout its life. At the time of my Oral B Professional Care 1000 Special Pack online purchase, it was by far the best price on the internet. That was before an additional $20 rebate being offered at the time. Shipping was <$3. This put it's replacement cost below that of some the thicker battery operated brushes. Overall, a good product and a good deal.
