This product seems to work fine, however I was under the impression that it was a package of 4 as shown in the picture, so please note it is only one cover included.

BV Medical Ultrasonic Dust Mite Controller

BV Medical's Ultrasonic Dust Mite Controller emits a range of ultrasonic sounds undetectable by humans or pets which interferes with the reproductive cycle of the dust mite, reducing allergens produced. Numerous studies confirm that a reduction in the Dust Mite contractions in the home produces improvement in the symptoms of allergy sufferers. Allergies can lead to other chronic conditions like asthma, eczema and/or other skin conditions. Simply plug the device in to an electrical socket.

I don't think this product works. Further, and this was interesting, I went out into the wide and wonderful internet to find a product that does. While searching I found another site with the SAME EXACT REVIEW as the one on top here. Er, that seems rather weird, doesn't it? Word for word, the same review? Guy must really like the product... Seems to me to be very dishonest to rate your own product and pretend you're a customer.
