I use them for half a year now and it appears they do the job as advertised.
I’ve been using 2×250g and need to buy another one since I started buying larger bags, and realised something. Fresh beans wants obviously to degass and I definitely notice difference after about two weeks, but putting fresh beans into airscape will drastically slow down degassing. I’ve been putting half of 1kg bag to the containers, beans left in the bag were “ ready” much sooner.
Do you put your beans straight to airscspe , those who are using them or let them degass first after you receive them?
