First off, I got the iridescent green and this piece is gorgeous and very well made. I've wanted and iridescent piece for a while now.
But I have to agree with the other reviewer, the mouthpiece is awkward and hard to get a good seal. Honestly, it's just too big, volume wise, inside to really control your inhale. I've been smoking 15 years and still have to clear this thing in 2 passes.
If the neck and mouth lost about half an inch in diameter to make it a bit smaller, it would've been perfect. I take it that's why the smaller version sold out so quickly. But if you have the lung stretch and really want this finish, this is for you. I still enjoy having this in my collection though.
