Airless sprayers are great time savers if the conditions are right.
Interior: There is some overspray. It is much, much less than an air sprayer, but expect to do a lot of masking, covering, protecting areas. I only use my sprayer (similar, but different brand) when the room is empty, no trim, and I'm spraying the ceiling. Walls only if same paint as the ceiling. Again, everything has to be covered.
Exterior: Perfect application of an airless sprayer. Use pieces of cardboard to mask off areas you don't want painted. Expect some trim touch-ups, especially if you don't have much experience with handling the spray gun. On the outside of the house a lot of painting can be done in a very short time.
Negative: After use, you MUST clean the unit completely, according to the directions. Taking short cuts will mean your expensive sprayer will be a one time use sprayer. Pay attention to the lubricant flush and storage requirements. I don't store my sprayer in an area that freezes in the winter.
Now if you knew all this and just wanted feedback on the brand... sorry for the verbiage...
