I have one, the 20 gallon version.
It is easy to clean and sanitize. I do not have access to fresh grapes, so my intent with it is to use it with must buckets. It holds 15 gallons must, which is 3 buckets and based on cost that is about all I want to do at a time.
I have done a syrah and merlot so far. I still have problems with the piston press. It can be difficult to get it to seat properly on top of the must. The last time when I hooked it up to vacuum all it pulled was air bubbles into the carboy.
I also had a problem with the outflow clogging before I started free run pressing. I had to sanitize my mouth and blow into the outflow tract to free the obstruction.
I am 95% sure it is operator error, but trying to troubleshoot while trying not to make a mess is frustrating.
In hindsight I am not sure yet how I feel about the pressing with the wineeasy,
