Review Content neat works great fun to make new Scents Im pleasantly surprised! I wasnt so sure about this item when I ordered it. One of the photos of this item shows the diffuser sticking out of a cigarette lighter on the console. I was buying it as a gift and found out AFTER I ordered it that the item would be used in a cigarette lighter on the dash, not the console. I thought the essential oil was dropped into a small compartment in the top of the diffuser and would spill out if used horizontally. I just received the diffuser today, and I am so happy with it! The essential oil is dripped onto a small ceramic-type disk(which isnt mentioned in the description of the product) and it comes with 12 replacement disks. The disk is then warmed which releases the oil aroma. This diffuser should work in any cigarette lighter. I wish I wouldve known more about this product when I ordered it. Im writing this review in hopes it helps someone else decide if this is the right diffuser for them! ONE OF THE BEST! I use this in my truck mostly. Thats what it was made for. Its better than buying all those hanging ones. You can use your scented oil of your liking and if you want to change scents, then you can get a new disk and put a different oil scent and plug it in. It works for me! Its attractive and I just love it! works! I really like this little gadget. I have it in my car to freshen it up with the essential oil fragrances I like. I have a friend who uses those horrendous cheap car fragrance smells and I cant even ride in her car it gives me such a headache. This little thing is portable and slim, and best of all, it uses the fragrances I like without being overwhelming. I love it.
