From this company I bought the two and one anti-snoring and air popper this piece of equipment shown on the Internet is not what they send you I contact the company and let them know that this doesn't fit in my nose properly what they told me was we cannot return it I can give you 10% off of something else So it's garbage to me now so I decided to take this apart to see the technology what is inside is two pieces of fabric that is it there is no technology with a showing on the Internet and what you're selling to customers is a bait and switch nothing but a rip off
