I have purchased many of Dream Scents wax melts & Reed Car Diffusers! They all smell so good & I can’t pick my favorite as I ❤️ them all! My latest purchase was Dream Scents Reed Car Diffusers ( keep in mind I bought 4) 2 for myself & 2 to give as gifts. I’ve had mine in my car & one in the house in a register. Dream Scents say they will last up to 4ish weeks, I’m going on 5 weeks n still have half the bottle left in each.. 😊 I recommend Dream Scents products over any other on the market….
