I used to own a magnetic pipe like the ones in the picture so I thought i'd tell you about it. Obviously they're discreet as hell and carry around and it has a gauze which some cheaper pipes don't. The problem with it being magnetic is that it's so easy to lose a half, especially considering that you're going to be high when you use it. Because it's so small it can get gunked up pretty easily and is definatly not the easiest thing to clean, so if you're gonna get it I definatly reccomend so pipe cleaning equipment. Also because of the size of the pipe and depth of the bowl it's can be a bit awkward to use.

Despite these flaws, I'd recommend it; it's cheap, discreet and more than does the job.
