Grover S. Harrisburg, PA
Made the installations yesterday.
The SpoutOff is a great product as it appears to do the job. We are waiting for a big rain storm.
The only suggestion is, the flange that goes behind the gutter would work better is it were 3.5 to 4 inches or the height of the gutter (this is true for my installation). The problem I encountered: The angle needed to seat the screws into the fascia board (in back of the gutter) was too acute to allow properly seating the screws.
I used an adhesive on the back flange and two screws on the front flange, it appears to be adequate to hold The SpoutOff in place.
All and all great product.
