they are about the same with cherryvape cannon only different are slimmer in size and i prefer this cannon than cherryvape cos the mouth piece top part are slimmer, better mouth grip! lol.....also....i bought 2pcs of pyrex drip tip which i broke 1pc when i force alittle more into 306 atty and it gave way n chip off so lesson learn here not to force pyrex drip tip too much.
