I am happy with the scent and this is my first purchase. My big concern was if it was OK to use with a cold air diffuser. I didn’t want ascent to break my new diffuser. My diffuser is the kind that does not use water and purchased it from Costco. I was happy to see that it is safe to use with a cold air diffuser. The smell in my opinion is strong and fills the whole house. I have two cold air, diffusers side-by-side and put them on the lowest setting one for eight hours. It fills the house 3500 ft.². The smell is not overpowering and strong. It is noticeable but not noticeable if that makes sense. You have a pleasant smell, but it is not like a strong overpowering tacky smell. If I was to suggest one thing to this company, that would be to have samples that you can get an idea of the smell that you like. I bought the my way sent and it does smell good. I would also like to try like the white tea that the Westin hotels use for cent. Other than that, the question I would like to know is if you buy the gallon size, how long will the cent last? I don’t know how fast it will burn through it and if it takes six months or eight months, I don’t know but at the end of that time will it still have a nice smell or will it be faded? So they say it is safe for a cold air diffuser, the ones that do not use water or heat up. If it is safe for that, then I am set with this company and how long does the scent last in the bottle if it is not used right away I run it on setting one for eight hours every day and there is a lingering scent that goes through the whole house. I like it and I’m happy even though there is a bit of sticker shock to the price of $319. The set up works, and I am happy with it. If they had a tiny sample pack to pick the scent that you like and then I can order a lot that would be easier.
