The mill arrived mostly assembled, all we had to do was attach the three locking latches to the lower bucket portion of the mill. The latches keep the motor and base together while the motor is running, and the latches also lock the two pieces of the mill together for storage (see pics). The mill is easy to manage and maneuver, due to it's convenient size and weight. 25 Liters sounds enormous, but it's roughly 6.5 U. S. gallons, so it's a bit bigger than a five gallon bucket. The mill is extremely easy to operate: just choose the sieve screen size and latch the mill together, then plug in the grounded - 3 prong plug, press the green power button and you're up and running. You can pour the grain in slowly or simply fill the hopper and let it do its job. When your done, or, if you need to change the sieve screen to another size, press the red button to stop the machine. Please be safe and always unplug the machine before changing the sieve screen, or your fingers may not be too happy. There are seven different sized sieve screens that come with the mill, they range from a fine - flour type finish, to a coarse - cracked corn type finish. This mill can be used to grind a wide variety of both grains and spices.
I wanted to do a video to go along with this review, so we decided to grind up a 50 lb bag of whole kernal corn, using the mill. The mill worked flawlessly and wasn't as loud as we expected. The mill did generate a little bit of dust that was coming out of the sides while running, but, it wasn't too bad. Cleanup was easy, I used a damp cloth to wipe the hopper and the bucket clean, followed by a drying towel to remove any moisture or residue.
Finally, a manual and a small wrench (for changing the sieve screen) comes included with the grain mill. The mill not only works great, but, looks good too. This grain mill is well-built and should last for years to come.
