I love this project sprayer. I've painted bedrooms, fences, furniture and the exterior of my house. I''ve had this sprayer for 2 years and still no complaints. I recommend to everyone as it is affordable, saves times and is so easy to use. I keep reading reviews that people have used it once and then it never worked again. I ran into that problem once, so I READ THE DIRECTIONS. The sprayer NEEDS to be oiled. I've found that if I skip this step, I run into difficulty, but as long as it is oiled, it works beautifully EVERY SINGLE TIME! The oil allows all the mechanisms to run smoothly without getting stuck. Also, I find that a latex paint thinner will help when the paint is unusually thick. All in all, this is a wonderful product that makes all of my projects easier. Great buy!
