Al P.: Nice product! I was disappointed that the seller would only sell me 6 sections when I needed 10!

GMC: I bought this to extend my aluminum downspout elbow further from the foundation of the house. I covered it with mulch and it is almost undetectable. I've stepped on it when using the hose and it seems really strong, not having cracked. This is the first year I've owned it so I don't know if it will weaken over time due to exposure to the elements. I'd buy this again.

Jerry: I used this product on one side of my house to discharge rainwater into a planting area and had good results. I plan to use it on the opposite corner to pass under a flagstone walk. This configuration works well to direct downspout output to target areas. Vendor delivered the product early. I am pleased.

Jake: Great product for light duty applications. The other line of StealthfFlow, the 4620 model, is better built and better suited for using if you plan on driving over it (riding lawn mower) or putting much weight on it; don't know the weight limitations though. The other line is a higher profile (not by much), the top is narrower than the bottom and the edges angle up to a flat top. The plastic is heavier and there are two braces that are on the inside.
BEWARE: Amazon has the products mixed together under "Frequently Bought Together" heading. This is the 4621 (Downspout Extension) and only fits to the companion piece, the 4601 (Downspout Extension) & 4631 (Corner). The 4600 downspout extension goes with the 4620 extender. They are NOT interchangeable, found out the hard way.
