I bought this window a/c month ago and prior to installing  I noticed a dent in the unit case. So check it out for dents as soon as u receive the product.  Have not used it yet to evaluate how well it cools but with hot temps on. Horizon I think I will know if it is any good. Looks about like the 22 year old a/c it is replacing. Don’t think it will last as long as the old one.
