Don't waste your money. Won't carry water.
Won't work on a steep pitched roof. Water overshoots completely, even though their recorded message says "will handle 2 feet of rain per hour". That is completely false advertising. Customer service terrible. I've been calling for months and have yet to get someone at my house. Said i was told my roof would be a problem when they installed, but I certainly wouldn't have installed if they had told me that! These are the most expensive gutters on the market and now I have to rip them off and put the old fashioned type back on to stop the leaking into areas that the overflow is hitting on the roof below! Incredible this could be the best on the market.
