Okay, so I finally got these SIKADEER RV vent insulators and WOW. They’re legit amazing. First off, installation? Literally took seconds. Just shoved them into my skylight and boom—done. No tools, no fuss.

Now let’s talk performance. My camper used to feel like a sauna in summer and an icebox in winter. Not anymore! These things reflect heat like a boss (97% radiant heat reflection—science!). The 3-inch thick sponge is no joke either; it’s like wrapping my RV in a cozy blanket.

The non-slip silicone dots are clutch too. Drove through some gnarly bumps last weekend, and these bad boys didn’t budge an inch. No velcro needed (though it’s included if you’re extra paranoid).

Pro tip: Let them expand FULLY before installing. Mine took about 36 hours to puff up properly after being vacuum-packed. Patience pays off—they went from pancake-flat to thicc insulation warriors.

Only minor gripe? My bathroom vent has a weird crank handle that makes removal slightly awkward. But for the price (way cheaper than camping stores!) and the insane temperature control? 10/10 would recommend to every RVer out there.
