A++++ works just like it should
Works great but don't break it while cleaning
For those not already in the know, these chambers are part of the appeal of the Puffco plus but are also very fragile...more than they look, certainly. The bottom of the chamber is actually a circular piece that isn't actually connected to the walls. By aggressively cleaning the chamber, it is easy to put too much pressure on the bottom plate, which pulls on the lightly soldered wires attached to it and break it. If you are careful not to put too much pressure on it when cleaning, then the chamber should last a lot longer.
All good as expected.
