I bought the device for Aussenrenovierunng my family home. Mainly so for exterior paint. I am quite well coped with it, only the strength of the neat exterior paint has the part to create something, 2 times that's probably clogged due to the toughness. After dilution with at least 5% water which was then without any problems. Good is the steady delivery of color, in general, the problem-free handling. If you are traveling on 3 scaffold levels, one must not always take the Paint Bucket, which facilitates the matter. And I would, however, have wished for a slightly longer tube, then that would have been perfect. The accompanying rollers are not suitable for very rough bumps. I have a relatively little structured plaster, there was no problem. In real Strukturputz the roller comes safely to their limits. The thick exterior paint has unfortunately caused extra effort even during cleaning. The roll axis I had to work extra something to the rauszubekommen Frabe, as the nozzles that must be rushing rob for cleaning. Ever is cleaning the sticking point, which is relative (time) consuming. Therefore, the device is really only recommended for large areas because it does its job very well.
