I'm due to report back on the Nira which I've been using since the beginning of the year - but I keep putting it off because I'm still not sure what I think of it.
The Nira was approved - in the US - for treating under-eye wrinkles but it can be used for other small areas elsewhere. You're supposed to use it daily and to see results in 90 days. It's very quick and easy to use.
I've been using it only on my upper lip lines. For the first three months I used it twice a day (which is permitted) but have recently dropped back to once a day. I think there might have been a slight, but not really significant, improvement. Overall, I'd say I was disappointed with the results.
One unexpected downside I found was that I became too noticing of my upper lip lines - looking daily to see if they'd improved or not. Clearly, not a great idea.
Angie (HotandFlashy) is still enthusiastic about the Nira. She has a recent video comparing and contrasting the three devices she regularly uses: NuFace, LED mask and the Nira. If she had to recommend just one, she says she'd recommend the LED mask.
