Good overall
Good overall. However there vent holes only in the top of the case and none in the sides, hence there is nowhere for air to flow from the fan, but up and around back into the fan. Same RPi runs significantly hotter inside this case than without any case. It really needs extra vent holes on the sides at the height of the heatsink+fan to allow air blown by fan to exit. Having said that, this case is still better than many other cases out there, and it is not hard to add extra holes. In all other ways this case is good.
