Water comes out from the holes. If holes get clogged you can remove the black tube on the bottom and remove any debris.

Can you leave them on during winter?

It probably will be damaged over time by freezing weather or severe sun. It is only some kind of rubber/plastic material. I rarely get freezing and snow, so I leave mine on year round. We rarely get freezing weather and snow where I live

Don't waste your money. How do they call this Frost King...
It kinda works in the summer, but is useless in the winter. It actually caused my gutters to backup. Luckily it was on my porch roof and not my home.

Twisted into a knot
I had this on one of my downspouts for two months before it twisted itself into a big knot. Totally not worth it. Just buy a expandable extender.

I'll make this short. The coil feature which recoils it when it is not raining is way to strong and it will not roll out when it rains. Not worth buying and I returned it. Also, where it adapts to the downspout is worthless also.

Took way too much pressure for the rain to unroll the sleeve in order for the water to escape properly. It would hold water in the gutter downspout and in the sleeve itself allowing it to gunk up. The 2nd rain that we used it, it made the elbow on the downspout so heavy from the rain that couldn't escape that it ripped the elbow from the downspout and water flooded the flower bed. Will not buy again and do not recommend. It doesn't work.

Does not work! Had to wait for our recent heavy rains to find that out. Took it off and used sprayer at the end of garden hose full pressure and the drain away does not extend. I think the tension on the automatic rollback feature is too strong. Water came out at the top. Returned gladly, even for store credit. I will stick with the regular roll out by Frost King and hand roll plastic back myself.
by Campbell
does NOT work as advertised
will not fully unroll causing water to back up into the downspout eventually pushing the product OFF of the downspout
