Yeah, thanks to the chaps over at the Money Saving Expert forums, I found out Colgate were giving away free samples of Colgate Total Interdental via their website.
And mine was delivered this morning!!! About a fortnights worth, so expect a review in about 2 weeks of my personal opinion on this product.
According to their website, they have run out of samples. Sorry guys
