Product review (5 stars): Using it in the winter, in northern MN
I read a review saying the profile for this was too low for the winter months.  Not a problem here.  We don't have a lot of snow but ice has been thick this year.  So far so good.  Super easy to install.  I'm glad I got it with the 6" insert too.  Wouldn't have known what to do with the end of the pipe if i didn't.
