We had Gutter Guardian installed on our gutters in 2004 and have had no good result.  The perimeter of the house below the gutters has a groove in the ground from rain merely rolling off the gutter guards and gouging out a trench in the ground.

Have called the company many times in a vain effort to repair or correct the problem.  Almost want to take the guards out of the gutters and go back to just removing the leaves each Fall.  This product is very unsatisfactory.  Any comments on what I could do here would be appreciated.  Thanks.

Here is what Gutter Guardian looks like:
