This is great to keep in a small room or a big room! It still smells throughout the room and smells amazing. We have tried different smells and my favorite is apple cinnamon medley. Gives out a great fall scent and can be a little strong if it’s in a smaller room but if you’re like me and can handle strong smells it should be perfect. I bought mine at Walmart for about $15 and it came with a spray! You just need double A batteries and it usually will last quite some time. The spray is set by a timer so you can have it go off to your desired time.
