Did not use the downspouts, I did not receive any. You do get a free cutting tool. I have used this on several coach's in the past and always have had good luck with the product. Before I made the decision to run this much gutter, I actually studied and even stood out in the rain and watched what was happening with the water. I am pleased with the results. Your application could be different for many reasons. Good luck.
