the machine is actually good, stable and easy to use, have painted about 200m2, no big problem. the only thing has to be mentioned is that the montage of feeding hose to machine is very very difficult! to insert the feeding hose into the machine is easy but the clamping ring used to fix the hose is very very hard to get in the groove. spent about more than 1 hour to get it fixed with help of a plier. the clamping ring is actuallly 1or 2 mm bigger than it should be. so I have to get the feeding hose constantly hooked on the machine, cause when it gets out, I dont think I can get it on again. can you please redesign the clamping ring?
