works great
this gets the water to drain away from the foundation, the last two feet have holes to get the water to spread out slowly and not create a rut, if its too long cut it!!!!! for 5 bucks you can't beat it, my down stairs was flooding because the down spout is right next to the foundation, this downspout extender is an easy solution, the idiots who wrote bad reviews did not read the information or look at the pictures the seller provides, this is a quality product that works very well, the only better solution would be to dig a trench out to the street and use 3'' drain pipe, I tried the spout extenders that roll up automatically and they dont work

Not the same as the 4’ extender
We bought 4’, 8’ and 12’ green Frost King downspout extenders. The 4’ is quality plastic, stays rolled up by itself and will roll back up after the rain (apparently. It hasn’t rained since we installed it). The 8’ and 12’ are flimsy plastic. They came with a flimsy twist tie to secure them. We had to replace those with our own zip ties. And they will not roll themselves back up and will probably get torn in the wind if we don’t roll them up quickly ourselves. Would not recommend.

Split within 4 months
Was just ok. Would not repurchase. It split along the seam in under 4 months of use. It did not stay rolled and only unroll with water flow so it was always very floppy into the yard. It would do in a pinch, but that's about it.

Solid product
Overall happy with the product. Works as intended. Had to duct tape pre-made holes at the end so that rain water didn’t spill out onto sidewalk but it does the job. Decent quality, holds up as long as it is not being tugged on constantly. No leakage. Good value for the money.

Look like it might be our perfect solution to conserve water off the roof and put into swiimming pool. Remains to be seen...New
We just got this to address a water conservation issue we are hoping to help. We are trying to use as much rain runoff of roof to add pool water. Our water in this area is depleting so rapidly and is very expensive and we have a ridiculously large pool (we are in Texas -- if you live in Texas in the summer to is a necessity--trust me). Our back gutter is within 5 feet of the pool edge. I will try to attaché a photo to show you our home grown rigging, but to articulate (sort of) we take a flexible gutter tube and run it through the hedge so we can get an elevated water source and then we attached this product. The produce is solid for the distance we need to cross the surround pool decking (which slopes back toward the house and requires the elevation being considered and rigged) and has holes just about where we need it too to go into the pool and down the side. I would be surprised if this retracts, but we do not care as we will gladly reroll it if this helps. Will try to let you know, but for now I think it has a great shot at working (ie I am a Pollyanna and always think my ideas will work until provden NOT.)

Sun deteriorates the plastic
I needed a longer reach gutter extension. The shorter reach extensions automatically rollup after the rain. This one automatically rolls out during the rain, but you have to manually roll it up after the rain has finished. Couldn't find a longer reach extension that rolled up automatically. Manually re-rolling after the rain is working out okay. Additional review: Nov 2024,After two months the sun deteriorates the plastic and the rollup falls apart. If located in the sun this will not work for you.

Can't be used in areas that have freezing temperatures
Kind of misleading to name your product "Frost King" when the directions say to remove Drain Away during the winter. Then what? I have a rain barrel that has to be drained for the winter and then I have to divert rain from the cut off gutter downspout out to the yard. I trusted because the product was named "Frost King" that it would work here in Western Pennsylvania where we get really cold winters with lots of snow and freezing temperatures. I threaded this very flimsy piece of plastic through a PVC pipe hoping this will keep the water off my porch and away from my house foundation. Also - I doubt those plastic ties included are going to keep the plastic attached to the downspout so I added a zip tie and then wrapped it with old pantyhose. I should have returned this item but it took a long time to drain my very large rain barrel and we are due for rain tonight so I had to get this situation resolved today.
