I like it!
Easy to install and flows water effectively, even in very heavy rainstorms. Test section installed a year ago seems to be holding up well. Doesn't eliminate the need to clean, but it's a lot easier to run a shop vac over the top of these once a year than to dig the slop out of the gutters a couple times a year.
I'm not sure how well they would do in an area with lots of pine needles or other junk that might stick in the foam, but I happily don't have that problem.
There's what looks to be a sprayed-on UV coating on the top surface that isn't applied as evenly as I would prefer, especially toward the ends. It will be interesting to see if the poorly-sprayed sections hold up the the Texas sun as well as the rest.
