Exactly what I expected.The air refresh system in the S550 works well and replacing the scent source is necessary every so often.My previous review was incorrect. Today I learned that my S-Coupe has a feature to control the amount of fragrance that gets released into the vehicle. Someone had changed mine; porters at the dealership. Just like they messed with my lights and turned on the horn when you lock it. For this reason, I had to revise my rating. #++++++++++++++++++#I have waited to do this review to be sure of how I felt about this purchase. I bought the last refill from the dealer and could smell it right away. It’s been a few weeks and I still have yet to smell this refill. The package and product look like authentic MB merchandise, but I can’t smell it. I’m not sure what is different this time.Smells great. My fiancée typically hates air fresheners bc they give her headaches. But I let this one running on full blast for a bit and she didn’t even notice it except made a comment on how nice the car smelled. Good stuff :)I priced these Cabin fragrances at the Mercedes Benz Dealership and they wanted $130.00 each. Cheaper on Amazon for sure. Good price and fast delivery. These Mercedes Interior Cabin Fragrance replacements last a long time too depending if you set the setting to LOW in your cars infotainment setting for the air freshener strength.I love the smell in the car I just think it's a bit pricey.I would find it much more attractive at $30 instead of a $100. It doesn't last very long one on highest setting.I recently purchased a used Mercedes and it did NOT come with air perfume freshener, so I had to buy one. It works great. I think I'll have to order another.Free side is a fabulous clean fragrance. Much less than the Mercedes Dealer price for this glove box air balance.
