I purchased these in the hope that we’ll never have cause to use them. We have an apartment in a converted Mill and ours also has a basement which floods from time to time. There are pumps in place and we have a sealed door, but I bought these so that we could protect our home a little bit more if necessary and I sleep a little better for having them! They are compact and easy to store for an emergency.
This product is for standby and security not one you would test and put away, I rely on flood shields product instructions and videos to let me know how product should perform
