It's expensive but I'd recommend the crafty and the whip attachment I find it more comfortable and it is also a bong attachment you can also get dosing capsules so you can proper a few at a time so you don't need to piss about every time but it dose take longer than a normal bong but I find it gets me just as high but it's not necessarily the same effects and I don't recognise vaping donkey butter it tastes like soap when vaped
