Dont buy them because their 45 day free trial is bull💩 it's the same company I've benn dealing with (CHOSGO)for months to get my money back, sent their earing aid back a week after I receive them, I followed every instructions given me in an email, and apparently they where at customs for weeks, yesterday I get an email from them and tell me that customs didn't passed them and I will get them back !!! Reason: The sender doesn't match the recipient !! ARE YOU KIDDING ME ?!? Of course doesn't match because : I SEN IT TO YOU !!! OH DID I mentioned that I had to pay 75$ shipping. So they got back to me and said : "Even if it's returned, our company will arrange a refund for you based on the circumstances. Please give me some time to coordinate. Finally !! I'll beleive ot when the money is back in my account !! DONT BUY IT !!! P.S. MOST POSITIVE REVIEW ARE FROM FAKE PEOPLE
