Just made a simple test painting a wall, the machine is fairly simple to use , the instructions are , good, except, the nozzle assembly wich the instructions are not clear enougth, the hose is long but is a litle bit stiff, I recomend to use some kind of braiding in the hose to prevent kinks and to cot the machine with some glicerine to prevent build up of paint stains, is much easier to clean afterwords.
The machine makes some noise like a pressure washer , but is in an aceptable level. it would be nice a link to buy spare nozzles.
Cleaning is paramount to insure a long service life !!!
