Query: Great - if you want fuzzy, pockmarked walls

Nothing is worse than a roller cover that makes bubbles in your work, leaving behind thousands of microscopic craters when they pop and dry, except a cover that sheds its fibers. This does both.After picking enough fibers off the wet paint and rushing to the hardware store in search of a different brand before my paint dried, I looked on the package for the note "satisfaction guaranteed or your money back". Guess what, there isn't any. Not only was this a time consuming and wasteful exercise, I had to sand the walls to cover the craters, free the fuzzies, and start again.I repainted with these:Wooster Brush R959-9 Painter's Choice Roller Cover 3/8 Inch Nap, 6-pack, 9 Inch. No bubbles, no fibers. Nice.
