This was my first Autoclave purchase & it did NOT disappoint! ?? The size is Perfect for a Small Farm grower. Very well made! I had to call customer service because the directions were a little unclear especially for a first time Autoclave user. Unexpectedly when I called the representative talked me through Step by Step and stayed on the phone through my entire first use! Very Few companies even do that anymore! The representative was Amazing, Patient and so kind! I was so impressed I HAD to share my purchase with my online Mushroom group! I would buy anything from this company!! Excellent is how I rate my purchase!
