I bought the NoNo Pro from HSN in 2016, and since then, it has not permanently removed hair. On top of that, it's stopped working no matter how many new ThermoCon heads I put in. HSN says they can't help and the NoNo site says I need to go through HSN.
So, it doesn't permanently remove hair, and it lasts about a year, and no one will back it up. So if you have a couple of hundred to lose, buy it at your own risk.
Bottom Line: No, I would not recommend this to a friend
