Beware - Melted within 5 minutes
Bought this to deflect a cent located behind a couch. Easy enough to install. When I went back to check on it 5 minutes later, it had melted. Returning it ASAP and back on the hunt for a product that works.

    I bought 2 for my sunroom. I tried one first to see if it fit to hold with the magnet cuz the old one from other home improvement had thicker stronger magnets while this one had 2 thin magnets. This product did not stay attached to side vent vent & slide downward. I plan to return & look for others with thick strong magnets.

    Works great, but required some modification
    The register vent I wanted to install this on has the open/close lever that actually gets in the way, so I was unable to mount this as is. I took a dremel to it and carved out an extra opening in the plastic and now it works great!
