Well, I've got to say grav has impressed me from the very beginning. To my first piece to this, I am just shook by the quality. This piece right here is a great for small sessions/personal use. With each inhale, you'll be thanking your throat with how much smoother this pipe hits than others :). I sadly dropped this pipe, but can confirm that the borosilicate glass is no joke. My whole piece stayed intact minus the mouth piece. Hoping I could fix this bad boy up again :)
