That's a great group. It was easy to install and easy to keep clean. I just used an old toothbrush, soap and water to clean it. I've had it for a few weeks now and so far there hasn't been any sign of the black coating peeling off. 07/10/21; A small piece of tape broke and now I have a small piece of metal sticking out on one side. I tried bending it with jewelers pliers. Although it looks like I'm doing more damage to the group. My group is now constantly clinging to my shirts and other clothing. This group was good for a while. Now it has become a bit cumbersome.
