I have a NoNo! but it’s an older on and not suitable for your face like the newer one.
Anyhow, I can tell you my experience and I think a NoNo does work but you need to commit to it.
I bought it when I was teaching classes so started off every 2/3 days…then MS caught me out! The funny thing is that when I get REALLY hairy legs i.e. long - it’s when they’re like that I notice that, I have massive patches with no hair
I guess if using on your face, then it’d be easy to use regularly, washing your face after is no problem - you do need to wash after as the smell is quite obviously burnt hair
It’s pain free tho and fairly simple tho so that’s my personal advice, be prepared to stick with it as it does work but does need a little time devoted to it - I think some people say it doesn’t work after trying it once. Common sense tells you that all the hair won’t be at the same point of growth on a single day. I bought mine after a friend recommended it - she had dark facial hair and said as a result, she loves the smell as she knows that’s the hair being killed off EBAY is my advice, a lot of people seem to throw the towel in quickly, I got mine on ebay and it needs an adaptor plug but cheap and works, the bits that touch your skin are the “blades” were in sealed packs.
I have loads of facial hair (blonde fluff) and I guess that might get a bit thicker with age but when that one thick hair on my chin turned white, I was delighted! So I was less than impressed when a 2nd, very dark one appeared. I was probably even more miffed as it was not that short when I discovered it, so I’m not too sure if anyone else noticed it
Anyway, sorry to waffle but after years of trying to shave, wax, epilate, immac etc.it seems like a sane choice
