The concept is great. My husband and I have a weird little boy-patio that has an opening smaller than the average door but I wanted something to put up so we could leave the back door open, allowing a breeze and our dogs to go in and out while blocking bugs. The magnets are pretty weak and for a while wouldn't stick back together after the mesh curtains had been opened, until my husband re-pinned them a certain way so they automatically draped back together. You get what you pay for, but if you can figure out how to pin them up, they work.
