A bit suspicious after the reports of fakes with previous deals. Also the normal ones are $15 for 3 (http://www.ebay.com.au/itm/Oral-B-Toothbrush-Replacement-Hea…) - I thought flossaction are meant to be more expensive?
Pretty hard to resist at this price.
Sorry but how much is the fake ones and is there any significant feature missing from the fakes?
