“I've come to the decision that I'm really not happy with my Fellow Opus, it does a good job, but the retention is a pain in the ass, and the anti-static stuff is awful, there are fines stuck to everything.”— Odd-Sun7447 on Reddit
“I bought a Fellow Opus, at the time it was the darling of this sub but the retention issues became apparent not long after using it. It's tough. I have a DF54 now”— bryguypgh on Reddit
