I recently got these silicone cup holder coasters for my Mercedes, and here's the real deal.

Fit & Functionality: First off, they *do* fit my GLC’s cup holders snugly—no rattling or sliding. The honeycomb design actually works; it catches condensation and minor spills, keeping the holder clean. But heads-up: if your cup holder is wider than 2.76 inches (like some GLE owners mentioned), these will swim in there like a tiny island. Double-check your car’s specs!

Material & Durability: The silicone feels premium—soft yet sturdy. I’ve tossed them in the sink after coffee mishaps, and they scrub clean easily. No fading after months of use, and they’ve handled both icy cans and hot tumblers without warping.

Aesthetic Quirk: They do make the interior look sleeker... unless your cup holder’s too big. Then it’s like putting a postage stamp in a cereal bowl—awkward gaps galore. For my model? Perfecto.

Verdict: If your Merc’s cup holders match the size (A-Class, C-Class, GLC folks—you’re golden), these are a no-brainer for keeping things tidy. Otherwise, skip unless you dig the ‘mini coaster’ vibe.
