tjm innovations llc gs-k536 36" x 5", Gutter Stuff Foam

I have been looking for a while for a single-piece to finish the job and found it here. Love it. For two years now I don't have to clean gutters, yay! I mostly have pine needles and this product works great for me. I cannot say the same about perforated plastic inserts...

The strip that I bought at the local home improvement store was 48" long, not 36", for $6.98. Same width and manufacturer. Fits well. I only bought one to try out. I will likely buy enough to fill the test gutter end-to-end and revise my review accordingly.
