Sometimes, changes in weather will cause the RainbowMaker (RM1588, RM1588H, RM1588-D) to un-stick to your window as the suction cup relies on atmospheric pressure to help them stay stuck! Cold weather, and cold windows, can have a harder time keeping a seal. Try waiting until the weather or window warms up before sticking again to prevent damage to the RainbowMaker. A helpful trick for boosting the suction cup grip is to run only the suction cup of the RainbowMaker under warm, not hot, water, then shake excess drops before pressing the suction cup onto the window.
