I'm skeptical about suction cups but they led me to believe. I took aluminum insulation mat, cut it to fit under my RV's windows, crisscrossed a few key holes, added a suction cup "handle", added a piece of clear tape to secure the "handle". " attach twice, and installed it on my windows. I was planning to wash the windows as instructed but rushed and installed the cups without doing my due diligence and they worked great. I recommend cleaning windows well, but I'm telling this story to show the suction power of these little wonders. They are also easy to remove.
