I put it on my MK3.5S and I'm glad. Better ABS overhangs and bridges. No increase in noise.
Could use a bit more volume at the bottom edge where flat and cone meet, for increased stiffness, especially important when peeling out of the buildplate. Worked all the same so that's not a problem, just an improvement suggestion.
It's not pretty and it obscures the view. But that's not it's role. I would consider docking at most half a star for it.
