Product review (1 stars): initially pleased, but now the brittle plastic is cracking and breaking
I bought this 3 years ago. It's functioned properly but the plastic has become extremely brittle. It's so brittle that I have to be very careful not to crack or break it more than I already have. I now need to order a new cover or go with a different vent system. I like the design but the cheap plastic is slowly making this product unusable. I would not recommend the product.
