Title: replacement heads @ drugstore.com
Review: Brushes well, but several months on, the replacement heads are impossible to find in the real world. I just stumbled upon them at Drugstore.com for $6.99 for 2 pack (I'm stocking up), although my local QFC has stocked them in the past at $11.99 EACH! Not to be paranoid, but this seems like a manufacturer's ploy to force you to buy a new device when the head is worn out. Come on folks! Isn't that taking built-in obsolescence a bit far???
Is the review positive or negative?
