I love my chimney vent...still have to just sand and paint a spot from the prior vent. The only negative is cleaning and reinstalling the filter screens. It is difficult to get them to line up perfectly and snap into place. Also cleaning them is such a pain! I won’t run them through a dishwasher for fear they will get discolored. Therefore I wash them by hand  instead. Those filter screens are the reason why I  rated this product a 4 out of 5 stars.
