Review on Grey Industrial Style Helmet Car Aromatherapy Fragrance Diffuser with Silicone Clip - Includes DIY PE Block for Car, Home, and Office Use by John Maynard

Oh my god, that's really good quality. That is hard. Not cheaply made. I added strong essential oils to the block prior to use. The reason I docked the star is because it didn't fit in my fiancé's car. It was too heavy for his vents, no matter how hard he tried to adjust them (he has a 2021 Tacoma). I haven't tried it on my old '08 projector, I think it will be better on my car. If not I will come back to update.
