I was looking for something more simple then an oil rig.
On dhgate are some different glass pipes. I have ordered this one:

Quality is good, thick glass, one pipe has a tighter air draw then the other one.
The outer tube is filled with water, this helps for cooling. I have changed the original coloured water to tap water. I don't have a jet lighter (can't buy refill gas in Cambodia), so I use a bic lighter which makes the pipe more of a session thing. Usually I only take one dab at night, I don't know about heavy use reliability.
The vapor has a good taste with QWET shatter. The pipe is a simple and cheap way to enjoy concentrates. The only downside is that it looks like a crack pipe
Somebody else uses a concentrate pipe and can recommend it?
