Its 9" to the tip of the mouthpiece. For $40, its a Hell of a performer. I've dropped all kinds $$$ on extra percs and such trying to bring my beaker to the same level of likeability. Always kept going back to this piece, eventually. Percolation could be better, but the cuts are clean and equal lengths. Durability is pretty good. Not 5mm stuff, but its definitely solid (size and the shape help). Very little drag, not on par with my MiO... but I can't expect that (also have to take into account drag from 2' whip). What you might want to try, to improve the experience, is seed beads (though they do add a bit of drag).
Here's the one and only video I made of it. You can see, my particular one pulls percolation to one side, on the light pull, but can rip some HUGE vapor hits and percs nice on the clear.
If you can hold out, I'd save up for that $135 Liquid Sci Glass bubbler, however. Though, that's easier said than done, my friend.
Hope that helps out with your questions/concerns.
