Product review (1 stars): Defective Bracket Mounts
Ordered two, and both arrived with defective bracket mounts. The mounting bracket for the top section is backwards and points towards the open air....away from the house. Making it impossible to mount and secure the top section. It appears glue holds the item together, so we're unable to turn or rotate the bracket to make them usable. Will be returning them. Very disappointed, love the idea of wind proof vents but in addition to these being defective, the plastic is brittle feeling and quite thin. I've shared pictures, so you can see the brackets are mounted opposite of the picture shown on the box.

UPDATE.....Amazon is really awesome, they quickly resolved the issue and issued me a full refund! Thank you Amazon for great service!
