E&B Lab Puck Screen

good

So far so good.
Reduces coffee oils from being drawn into the shower screen. This ahould reduce frequency of backflushing
No impact to the taste or extraction of espresso.

Didn't understand the hype around an extra screen when there is already one on the group head. Consistently less stray spray from naked portafilter. Pucks are perfectly dry and formed (I know there are other factors - I weigh my doses). I am suitably impressed by the lack of coffee debris on my group head after pulling a shot. And to top it off, the magnet is a very nice touch. The screen easily lifts from the portafilter with the magnet after extracting a shot. It consistently works well. Don't have to dig the screen out of the knock box. Nice touch indeed.

I like this quite a bit. Super easy to clean. There’s not as much thickness as a mesh screen, so there’s more headroom and some retained water on top, but doesn’t affect shot taste. The magnet is very fun to use.
