Zero Retention Single Dose Blow Up Hopper

It's time to get rid of the hopper and upgrade your equipment with a single dose blow up hopper.
Blow Up Hoppers are designed to blow the remaining or coffee retention from grinders.
In my video today, I find that it worked okay but there were still retention that I used a brush to brush the remaining out.
Any recommendations?

Hello, it's better the grinder is working when you blow up!
The grinder is a Mazzer mini, right? Where have you bought the blower and does it fits well with the Mazzer?
Thanks...
