Query: Causes condensation inside the car

This cover became completely useless.Leaving our car outside with this on caused severe condensation to pool inside the car and messed up our CD player and electronics in the car as well.Hoping once everything dries out that it will be OK.Don't know if the cover would be OK for indoor use, but that kind of defeats the purpose of why we bought it.In other news: it fit the car fine and the bungy thing, although cheap, kept the cover on with no issues.
