Packed well, arrived quickly and installed in a cinch. My only recommendation would be to post a picture with actual dimensions of the box for the rough opening and of the outside of the trim. It would help those on a tight a schedule who have to cut the whole before the product arrives. Otherwise great overall experience. I will be purchasing more of these in the future

Tried multiple times to call into customer service to discuss product before purchase. I finally just had to order the product blind and wait to receive it to answer my questions. They did have the best price for this product.
