I have purchased most of the Worx Maker X family of tools. My usage is probably a bit more than the Worx intended for the Maker X system, but since I already had a few Worx tools and batteries I decided to give these tools a try. So far I would rate the devices from one to five for usefulness and functionality. The paint sprayer is by far the worst. The paint container is tiny, although honestly you can see it in the photos. The air pressure seems really insufficient. Instructions are minimal with no clear guidelines on how to use the right colors or how much thinning is required. I tried different colors diluted to varying degrees. It took a lot of thinning before the paint even spattered. The spray pattern at this dilution level was terribly erratic. I ended up with large drips and other areas with little to no coverage. I've tried all sorts of adjustments, but it didn't do much. Maybe more detailed instructions would have helped, but my experience with the other three types of atomizers quickly put me off keeping the Maker X and I sent it back for a refund. The device was easy to clean. I couldn't figure out the battery life, but I suspect it would be fine for small projects.
