Don't buy the Oral B's....Get these!
They are as advertised.  They were delivered on time.  My ONLY complaint is that (and I suspect this is because they are &#34;after market&#34;) they seem to get loose on the mounting fairly quickly.  It doesn't stop them from doing a fantastic job, but it does set up extra vibration that is a bit annoying.  Still, if this is the kind you need, as far as I'm concerned they are the only game in town.  The Oral-B brushes that are still out there for sale are atrociously priced!
