Review on 🚐 Dumble RV Skylight Insulator - 23 x 15in Vent Cover for RV Skylights and Shower Vents with Insulation - Ideal for Campers and RVs by Brian Lee

Well it looks like this foam 'insulator' is about half the thickness of what is shown and described on this Revain page. It is expected to expand to its full (announced) thickness within the next 48 hours. However, I have examined the piece of styrofoam inside and am of the opinion that this is not the case. It seems to me that this is just a scam claiming that the foam will eventually "expand" to its effective and "original" thickness. I think they ship semi-thick products claiming that due to the vacuum packaging they are just crushed. If this thing actually expands enough that I think it just got squeezed, I'll definitely change my rating.
