CT, first, thanks for your contributions. I participate in this forum because there are virtually no "attacks" on participants. The first post on this forum was by a virtual newbie. I think we are reacting to your post because your view was so concise and definite. If read directly, the newbie might have run out and purchased OEM mirrors. Others, including me, have 3rd party mirrors that don't vibrate etc. and are much less expensive. When we voice that opinion it is the same as yours, it is meant to be productive. I think that some of us believed that the wording you used was too strong and too limiting. This isn't a personal attack, we are just reacting to way you communicated; there was virtually no room for a discussion or disagreement. And, this is a relaxed forum, so please also give others a break as they might have posted words that appear to you to be an attack, yet they were also just trying to communicate their strong views based on their experience. There is so much on this forum to learn, hope this may help.
