double chamber bong

[Meduzz]

does anyone have experience with a bond with 2 reservoirs?
i'm planning on buying one but i don't know if it's like better than a normal bong or if you have to do more effort for a good hit.
heres the one i might buy (its kinda cheap and it looks cool)

Sure, I have one with 3.

I, myself, don't care for metal bongs, I like glass.

That little one that sticks out in the picture; we normally call those ash catchers; you can buy them separately to add on to any bong in place of the regular bowl piece. They keep all the nasty crap from getting into the bong and it's easier to change the water out. But, no, there's no extra work or effort involved.
