Review (5/5): Great Brush Head
This is Philips' best brush head yet. The smaller profile is much better at cleaning hard-to-reach places. While I can't really say I felt water and toothpaste being directed between my teeth, the HydroGuides definitely feel great along my gums.
To the previous reviewer: of course you still have to floss! The product description never claims you don't have to floss; it says "...get closer to the benefits of flossing". There's a difference between directing toothpaste and water between teeth - as this product claims, and actually cleaning beneath the gum-line, which can only be accomplished by flossing.
