So I got them and I removed one from the pack and hung it up in my room. It was a bit funky in there so it was a perfect time to try the product out. By the next day the smells were gone. The only thing I wish is that they were bagged individually because I can use one at a time. They are supposed to last 2 years. I think it's a good price range for 6. It is also a good product.
