Works great on my mignon crono. I am not using it with a bellows. I might get a wood lid from etsy, but nice to see through the top with the clear lid as well.
With the addition of the "bellows" most of the air escapes through the hopper gate slot in the side. I would suggest buying an aftermarket single dose hopper without the gate. Quite the over sight from this big of a brand and at the cost for these add-ons.
Thank you for the quick service, love the items perfect for single dose shots
