This is for those with machines that don't have a 3 way solenoid. Lever machines, or smaller machines are a good use case.
It's a silicon tool designed to fit in any two-lug portafilter slot and spread the water around the shower screen and the area near the seal during a flush.

Looks interesting. I know a couple of people who've put in an order. Will report back.
