Query: Careful of the roller assembly

I have used an earlier design of the Paint 'N' Roll for years and liked it. I wore it out so I bought a PaintMate to replace it. Big mistake. As far use and cleaning goes, it is virtually identical to the Paint 'N' Roll except the roller assembly was redesigned to snap together instead of screw together like the previous design. During use, the roll tends to come apart, drenching the floor, the painter and everything else.I've looked at all the newest Wagner painting products and they all use this same design. It made such a mess that I fixed the crack in my old Paint 'N' Roll and am back to using it.I wouldn't buy it again. I like the trigger feed so I'm going to adapt it to my old one.
