My batch of new rollers were "dirty" with foam residue which left trash in the finish. The roller "hot dog" shape appears to be cut into shape rather than molded. The rollers did not fit the recommended roller frame properly. They were too tight and would bind causing the roller to "slide"; not a good thing. I do a lot of painting with two-part urethanes and was hoping for a quality mini roller better than the good ones at [@]. These here are not good for finish work, maybe primer and base coats only. They are a fine tool, but the quality is just not there.
