I posted this reply in another thread about the TRIA:
I have only read bad reviews of the NoNo, but have not tried it myself. I did recently buy a Tria Home Laser hair removal and it Has. Changed. My. Life. I bought it from QVC and it has a 90-day return policy so I thought that would be plenty of time to give it a fair try. It doesn't work for everyone but it is working for me.
I have very dark black hair all over my body and fair skin. Apparently this makes me an ideal candidate for laser hair removal so this device works very well for me. I use it more often than recommended on the package, and I am also using it on my face, which is not recommended, but after only 3 months, I have seen an absolutely DRAMATIC reduction in hair on my face and bikini area. It is a small device, which makes doing my legs more time consuming and difficult, but I'm still working on them bit by bit. I don't really mind shaving my legs and don't get the ingrowns as much as I do in other places, so I'm a bit lazier with the laser on them.
The other drawback is that it is painful. You can adjust the settings but for best results, you should put it on the highest setting you can tolerate. Not what is comfortable, but what you can tolerate. So I put it on the highest setting and maybe I'm a wimp, but I think the pain is relatively intense. My only advice on that is to do small areas at a time, take a break, and then chase it with a cool cloth or ice pack. It has gotten less painful over time of using it, probably because there is less hair to "zap".
It is expensive, about $400, but considering how hair has plagued me my entire life, it has so far been worth twice the price to me. Laser hair removal in a salon or dr. office is much more expensive. I was paying $170/month for waxing just my bikini line and face. Seriously. Plus, unlike the NoNo, you don't have to buy any replacement batteries or cartridges or anything. It's self-contained.
