I love, love, love this piece. I own a number of Grav pipes, but this one is truly special. The shape, design, and function are all marvelous, and there is nothing I like more than taking a draw and watching the bowl and stem turn a milky blue-green before I take a hit. It's so easy and reliable, it's quickly become my go-to piece and I'm ordering a second as backup. // I hear those who have received cracked pieces. My first order arrived in two pieces (ugh), but I alerted GRAV, and they quickly replaced within days, without cost. It's a pity that it is so fragile, but this is quality blown glass with a fine stem. Handle with care. That said, the piece works so well, it's still worth 5 stars. I feel like every smoker should have this guy on hand.
