I've been using Dasiy glass screens w/ stem for the last few years to great success. I came across these honeycomb glass screen discs one day and figured I'd give them a shot. I got the green to match all the other greens on my Diamond Glass piece. The disc is 8mm wide and fit my bowl perfectly. Up until now I had been using a 8mm Daisy w/stem glass screen but wasn't getting a real good hit. I bought these and it fixed the drag issue by getting rid of the stem and replaced it with a half a dozen holes that are drilled in the disc. Cool little screen that's a bit pricey but as long as you don't loose them then each screen should last a while.

1 word: Airflow. No other screen I've ever tried gives this good if airflow while still stopping so much ash from entering your piece. Truly awesome, and they fit pretty low so you can still pack your bowls to the brim!

Doesn't really fit. It just sits there . There is no "nub" or arm to hold the screen in place. Slides around in the bowl.

It's good for some bowls. Other than that great air flow.just after few usages I recommend poke the holes with paper clip or toothpick for it can work brand new lol
