Nice fit - Jon - 16/02/2013
I ordered the red one, and it fits over the 306 really tight and snug. Dripping into it is a breeze. Will probably get the 'posh' metal one on my next purchase.
Poor - Jon - 22/03/2013
Ordered the Cannon Drip tip. Unfortunately there was quite a nasty mark on the drip tip, the plastic casing comes out and basically it's right mess and a waste of money.
