I have one also and it works well. It took a little while to get used to it. Its the only mirror on my car now. I looked at the Wink mirrors but as Rod pointed out, they are taller than this one and block too much of your forward view.
BTW, the person behind the Mirrors for Sevens is Bob Simon, a member of this group and an all around good guy.
Its a well made piece and I find it easy to adjust. It does worry me a bit when I let someone else drive my Se7en as I don't think they pay much attention to the mirror. But in a Se7en, in the words of a famous Italian driver "Whatsa behind ya doesn't matter".
