I currently have five Spoutoffs on 5″ gutters that work beautifully. We have lots of long pine and short fir needles to deal with here. A heavy rain will flush all down The Spout making me very happy when I see the pile at the end of the downspout.
My remaining project is on the backside of the house, a 50′ run out one downspout. My plan is to utilize The SpoutOff here too.
Guess I’m being a little gabby, but the bottom line is you have a fantastic product!
