[This review was collected as part of a promotion.] My last Sonicare died, and the replacement I had, I could not just buy a new cord for (a separate issue), so during Prime, I ordered my new Sonicare. It was pricey, even on sale, but so far it's doing well. It had a short learning curve (took two uses to get the hang of it), but it's doing reasonably well. I like the ability to increase the pressure, though it's not as good at whitening as my last one. I'm also concerned about how much the replacement heads will cost.
