So I bought one of these to give it a try so I could have some real world experience with this on my own home, in Toronto.
It attaches securely to the end of the downspout or elbow easily with a zip tie provided.

As it rolls out with the water pressure from the downspout it slowly unwinds and lets water out the little holes until it rolls out completely letting all the water out the end where there is a big opening.
Once the rain stops the spring inside the plastic hose will retract itself back into its original compact shape. We had a big rain shortly after it was installed and it worked as promised on the package and retracted almost completely to its most compact size.

Limitations of the Rainguard:
1. It seems that on a light rain it will not uncoil very far from its compact position which depending on your situation may not be far enough away from the basement.
2. The little drainage holes on the top of the Rainguard are located close to the start which may be too close to your home.
3. Its thin plastic and the day after I installed it I came home to see that the grass cutters have whipper snipped the side out of it. So much for the longevity factor. Its fragile construction is likely why I have yet to remember finding an operating Rainguard on someone's home.
4. A brisk wind may blow it around as it's fairly light.
Since the one I purchased got damaged so quickly I saw it in action but never had a chance to record it, I have linked to the manufacturers website where they have a video of it in action.
