First Time User
The ProX21 was recommended as I have never used an airless sprayer. My experience was good however, I was not expecting so much paint dust nevertheless, this being my first time using this product I will say the finish result is Great. So the next time I use my ProX21 I will prep even better.

Thanks for providing your feedback. The ProX21 and ProX 17 are not the same sprayer in terms of spraying power. The ProX17 is rated at 3/4 HP and the ProX21 is 7/8 HP. Also the ProX21 is solvent resistant out of the box.

Fast setup and cleanup.
I am a professional painter and this is my 4th Graco Airless sprayer.These are great performers that can deliver paint fast and effeciently. Easy to setup and clean. Parts and accessories are readily available and reasonably priced. If you clean them up after use and maintain them properly they will last a long time and offer great return on your investment.
