Noticeable difference

Way better than the standard 6 slit downstem works great at diffusion in a 10 inch beaker downstem is 3.5 inches long.

Great piece

Phenomenal function. I gave it a 4 because I like a bit more chug in my hits but if you like snappy hits, then you'll like this because it gives percolation without reducing airflow!
