I would give it a zero rating if I could.
I got the NoNo Pro for Christmas, so didn't check the reviews ahead of time. It burned me twice, I smelled like burned hair after each use, and I never had a satisfactory result from it. I read the letter that came with it, and it gives a window of 15 days to return and get a refund. It should be more than 45 days, and less than 60 days from receiving it. I am now in that time period, and have called them twice. The first time, the lady said she would send a return slip to my email. I waited two days and didn't receive it, so I called again, and was told once more that it would be sent. I had the representative wait on the phone for me to check my email, but it never came. Then he asked for another email address, but it didn't come there either. He then said that he would mail it.
I have been waiting for five days, and still nothing. I will call again, but don't know what else to do but mail it back without the slip. I don't know if I will get a refund or not. Very, very disgusted with the whole thing.
Bottom Line: No, I would not recommend this to a friend
