The Bonsai 25Q Fully Automatic Electric Pressure cooker has impressed us right from the start. This table top workhorse has some impressive features not found at this price point! The Bonsai 25Q Sterilizer heats up and builds pressure in 25 mins...

Great So Far

I have been using this autoclave for a few weeks now and I’m pleased with how it’s working. A single run can comfortably handle 14 quart jars or 6 five pound bags (Unicorn A14 size). Overall this is a better capacity than what I could manage in my All American 50x electric benchtop unit.

It does create a strong vacuum after cooling down, so opening the valve does need to be done in front of a flow hood so contaminants aren’t drawn into the vessel. Alternatively, you can soak a paper towel in rubbing alcohol and wrap it around the valve before you open it so that any air drawn in by the vacuum is “cleaned” by passing through the paper towel.

The digital thermostat is a great feature. I like not having to babysit the unit as much as the All American. Once it has completed its timed cycle it turns off the heating element automatically, so you don’t have to do it manually. The construction of the vessel is much thinner and feels less sturdy than the All American. This autoclave is clearly being manufactured in Asia, so if it ever needs to be serviced/repaired I can only hope it is as simple to do it through Midwest as it is to get an All American serviced through the manufacturer.

For the price point and capacity I am happy so far. I hope the unit has a long life.

Set up is fast and this baby has some power! My first trial was some grain jars and 20 minutes later I saw the steam shooting out the top vent, which then you can flip it to start building pressure (after venting the hot air like a normal pressure cooker) and it was at 15 PSI within 10 mins after that. It holds the pressure at which ever temp you set, for me I chose 120 degrees Celsius, which is 248 F, but it looks like you can go way higher too then any Presto or All American pressure cooker! The timer started when it hit the temp that I set and I ran that for 60 mins and when it was done it had a beep beep noise which I just turned it off, I always let my jars or bags naturally cool in the cooker. Overall really a great unit for the price! Can't touch that price compared to anything esle Electric! Fits perfect on my bathroom floor and now my roommate does not get pissy when I use the stove at night!

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!
