This is the WORST thing I have ever done.Cost me a fortune to have installed and it created the worst nightmare. FLOODING in the basement and water FROZE on my front steps the entire winter,This DOES NOT WORK. It just holds water and junk and weighs down the gutters, No wonder you do not see Home Depot or Lowes carrying this product.
BEWARE: WHEN YOU CALL THEM, THEY HAVE THIS STUPID PERSON WHO NEEDS EVERY PIECE OF PRIVATE INFORMATION FROM YOU AND THEN SAYS, WE'LL HAVE SOMEONE GET BACK TO YOU. Do they return calls?NO THEY DO NOT. Stay away from this company and this product. I wish someone would have warned me.

He is of course referring to:
