... Is rather mediocre. The adhesive force of the magnet is really good. I think with 4 magnets a slight protective tarpaulin front of the mobile home. Bad is the hook, which is actually pressed inward and then returns by spring action. Even when careful threading into the eyelets of the tarpaulin of the carabiner has been overstretched and worked outward instead of inward. I wonder when the hook completely fall out. Too bad, otherwise actually a well thought out product.
