by a hitter, splurge and spend two or three dollars on one that looks like a cigarette, they are the perfect sixe for a hitter. if you are smoking good weed it shouldnt take more than three to get you high, and probably less than that. it takes about 1 second to pack. i have one and use it frequently it doesnt get too hot. if you are smoking and trying to save money hitters are the way to go. sure bongs/bubblers are more efficient, but they also use up a lot more weed and cost more and cant fit in your pocket. trust me a cigarette hitter sounds like just what you need. plus you have the whole discreetness thing with it, which i know doesnt mean much, but it cant hurt

if youre looking for something that is really small and cools smoke, as far as i know it doesnt exist. yes there are small bongs and bubblers but nothing that could comfortably fit in your pocket.
