Had bought the sunscreen to protect children from sunlight least bit. When the shipment arrived, the suckers were so bent that they were absolutely useless. So cheap, so much plastic, so having a bad sucker I've never seen! When I then with another suction cup (I had of old sunscreen parts) have been trying to push the thing at the window firmly, the protective film is already torn !! Incredible scrap what is offered here! Please begrudge you few euros more for something useful!
