Summary: This is my first electric toothbrush, so I don't have much to compare the Sonicare to. The item is pricey, and only time will tell if it holds up. It is easy to use and seems to clean my teeth better than my manual brushing did. I don't use it every day, as it takes a little longer to do a good job than a quick manual brushing. All in all, a good product.
It is good but probably not worth the difference in cost from the base model

Summary: I used the previous version on Sonicare. This model is lighter and my previous model did not work strongly after several years. I do brush longer than the 2.5 min on the white mode and think I could have done just as well with the lower model. I did not understand that the write mode was just an extra 30 seconds on the timer. I am happy with the performance.
Summary: The carry case design is a significant improvement over the one provided for earlier models of the toothbrush. Longer lasting brush heads would be a big improvement so that one need only change brush heads twice per year rather than every few months. I hope The soft material on the handle last longer than on previous models that flaked off with only light wiping with a clean cloth.
