Query: Not loud enough

After reading the reviews, which seemed good I purchased this for my husband who is a day sleeper. It was quite smaller than I expected and was not loud enough to drown out any noise. The a/c unit in the room he sleeps in was much louder than the Sound Conditioner so it was of no use to us. However, I have to commend the customer service. They are great! We had some problems tracking down the package and had to contact them. They replied quickly and even checked back with us to make sure we got our package. Later after I returned the item (which was not a problem) they sent an email confirmation to let me know the transaction (refund) had been taken care of. Even though this purchase did not work out, Hands down they are the best with customer service and we plan to order from them again soon.
