SEP, Smart Espresso Profiler with a G 1/8" male connection (used for a La Marzocco Machine). It currently has a full battery (newly installed last week for testing) and should last 18 months. I will include a couple older batteries that I still have that I tinkered around with.

Price is $350 which includes shipping within continental US.




And here is a video I took of it in use a couple days ago.
