I saw more bad reviews than good on this roller. but i said ill try it. i paint bee boxes we buy plywood in bulk 4x8 sheets, i tried the airless sprayer made a hell of a mess tried the old type roller took forever. I tried this. it is the battery operated filler tube. i was astonished it was so easy perfect coverage even and smooth. Took a fraction of the time to paint and the clean up was a breeze..The main thing with this roller be sure you coat the orings with included lube. and clean it very well after use. No reason it shouldn't last for years I am very pleased with its performance i dont give but a few reviews on items . This is a great system highly recomend
parts that are less efficient. these components are easily damaged this component is difficult to find in existing store stores. components that are easily damaged i mean part of the rubber cover so that the paint does not come out of the paint suction hole.thanks
