My first perc and it's great. A little blemish in the glass but it doesn't affect performance. I use it on the beaker base with ice cold water, the triple pinch mouthpiece filled with ice cubes, the Helix pre-mix chamber and a triple pinch bowl. It's so smooth you have check the bowl to see if it's done. That combination is so cool on your throat it's like taking a breath on a winter day. Another great Grav product added to my growing collection.
