You see these anit-snoring devices that are placed in your nose. What a RipOff. These come from China and cost about $.50 to make. Rama Deals goes by various names so you don't know who you are dealing with. This device cones in a box with the the title "Air Purifier" and only last about 6 or 8 months. It has no manufacturer date or expiration date on the box. When you try to return the iem (and you will return it) they require you to pay for the shipping and deduct their shipping from the credit you receive. This company is a RipOff
