Review (1/5): great product, but broke after 2 years
I just received what was supposed to be the Deluxe 8850 DLX Oral-B, but like another reviewer, received just the Professional Care 8850, which seems like the Deluxe version without the attachments (I hope that is the only difference). This apparently happened to other people too, so if the attachments are important to you, you may want to buy this elsewhere or risk several cycles of buy/return.
Having said that, the one I got looks pretty much like an updated version of my old Oral-B brush that I am replacing (battery finally died after around 7-8 years)--and I loved that one so much I was desperate to get this new one when it died!
