OK so a few weeks ago I was making a order with dx.com for some Christmas stuff (lighters) when I found these. now at the time I was still having trouble with drying and tamping and rarely ever get the the bottom of a bowl so I figured these would help finish all the baccy in the bowl.
but I was very wrong I tried it yesterday and there is a few problems.
1. is it give a very loose draw not controllable with a tamper.
2. after getting tired of it after 1/2 a bowl I pulled it out to find a wet juicy mess under it.
I figure if you actually smoked a whole bowl you would get a ton of moister and gurgle.
so yea that's my 1.80 lesson for the week "if it ain't broke don't fix it"
I am so glad I have got my Technic down a lot better now and finish a bowl all the way down.
