## Questions & Answers

**Q: Will this work below 32 degrees?**
A: No
Plus they don't work very well at all.

**Q: Will this work on 6 in down spout?**
A: No. It’s for 4 inch

**Q: How can i tell if this will fit around a 5" downspout**
A: No it will not fit a 5 inch downspout. I bought it believing the other answer and learned the hard way that no matter how hard you stretch it, it won't fit.

**Q: What is the round plastic piece for? Does that go on it somehow?**
A: I was totally unhappy with this product. Sorry, I don't remember the round piece. The unit did not stay attached nor did it unroll during a heavy rain.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very functional
*by P***Y on August 3, 2025*

Worked as expected

### ⭐ This does not work!
*by A***R on December 30, 2020*

I bought this because I just put in a walking path around the house, and the downspout was letting water to the path which is too close to the house. The product says it is fit universal, but my spout is 3*4 and it does not fit. This was the problem number 1. I cut open the top part of the plastic and forced it up, but the zip tie came with the package was so weak it broke immediately. This was the problem number 2. I used tons of duck tape, etc. to wrap it tight to the spout. But today when it rain, I see that rollup part wasn't extending all the way. The water inside build up and spilling upwards from where the plastic is over the spout. This is the last problem before I cut it open and thrown it out, and put back the elbow. Such a waste of time and money. I do not recommend this to anyone.

### ⭐⭐⭐ Doesn’t work well for our purpose
*by A***. on October 25, 2021*

The fastener provided did not hold the extender on when it rained, so had to reinstall using a zip tie. Also, it only rolls out to the extended length when it is raining HARD. If the rain is light, it rolls out only about 4-5 inches, and the water comes out the perforations along the length. That caused mildew to form under the plastic on our sidewalk. We had bought it to extend from the gutter, across the sidewalk, to the garden area. So for our purpose it did not work well.
