I'm very disappointed with this product! I purchased a set that was listed on my Amazon Wish List in December, 2012, from BuyItNow.com. It arrived at the end of May. Two weeks later after installing it and waiting for rain showers, another unit began leaking water by one wall of each shower. This has continued through to now, July 2013. The other two units remain dry. Buyer beware, these products will only last about 9 months max. Don't waste your money purchasing anything like this.
