I did not get what I expected. Because of the photo, I expected something that looked like pretty stones, and not a small plastic box with a venting system. What is contained is a soft block of material that is supposed to absorb odors and pollutants. I am not sure if it works yet, because I just got it yesterday. I will update my review accordingly later.
I read the reviews before I made my purchase, and generally, they were highly positive, so time will tell if it does the job.
What I am not fussy on, is the smell. It was supposed to be light, but it didn't seem like it to me--I am not a fan of fragrance and notice it easily. I can smell it too much even though I have the vents open only a tiny bit.
I will keep it to see if it works, but I am very glad I did not buy the eucalyptus scent, which I thought would be even stronger.
I'm not sure if I would buy it again...leaning to no.
