I haven't used them yet. I needed something to prevent water from going into my basement garage. We were to take water from Hurricane Helena. I was outside digging trench the day before. My area missed the bullet. Had we not, however, my house would have taken in water. I am looking forward to having the next time threaten weather comes. I plan to use them in the carport and a couple place that receives alot of water flow next the house. I like how you can put it into the garden when the bags become old. Which they can be used multiple times. I love the easy storage too. I have them in my basement ready to go. I also bought two more boxes without the plastic container. I feel better knowing that I don’t have to store large containers. Be sure to read directions.

I live in a flood zone in my community, these work really great to keep the water out.
