Removing a side mirror

They really come off easy, you just have to take care

BUT....

the other option is just cut them off and buy new.

You were right. It was easier to remove than I thought it would be. I've encountered these devices before. I either mangled/destroyed them and typically, cut myself on the sharp edges while doing so. Thanks all.
