Geeez ..... Oral-B
are the same company?
They must have some powerful sub-liminal product synergy in their marketing, because all 4 of those brands get some heavy business and brand loyalty from me. Toaster, coffee-maker, razors electric and regular, toothbrushes (both electric and analog) and batteries in everything I own, even in the keyboard and mouse I'm using now ...
And I thought Oil company mergers were outta control ....
