You mean it actually works? In all seriousness, and fairness, according to the website 'Consumer Reports,' it actually took longer to use the No! No! hair removal system than it did for people to shave. Furthermore, people widely reported that using the device didn't take all the hair cleanly, as many people felt their skin was prickly.  More about that in a minute, but now let's take a closer look at the No! No! hair removal device and see how it works.
The No! No! is said to be able to be used all over your body, which is an advantage compared to thinking about that type of coverage with a razor. It is supposed to be completely painless, and the actual process of removing hair is handled by a pulsing 'Thermicon' heat technology. You are also provided different accessories for your No! No! including both small and large tips, cleaning brush and a small and large buffer. 
It is important to know that there are three treatment setting levels for this device, the standard low, medium and high. As for more description on 'how' this device works, there is a heated wire for removing the hair, of course utilizing that Thermicon heat technology. When thinking about using this device, do you feel a little cautious? It's different, so to explain the process further, you hold the No! No! at a 90 degree angle, and the device is set up to glide properly over the skin. What's great is there is a light that comes on if you're doing it wrong, so that makes it quite simple. It's important to point out the use of the buffer, which is also why the No! No! takes quite much longer to use than many people think. The buffing must be done after you have finished the hair removal process; otherwise, you're actually leaving what is called 'crystallized hair' to sit on your skin. 
You might be thinking that the prickly feel felt by the people mentioned on the Consumer Report website might have been due to not buffing; however, this is a reputable agency whose study involved many people and lasted for a total of six weeks. The link is provided below. I took a look at the reviews, and they are completely mixed, many good, many bad. They are so varied that on HSN, the Home Shopping Network, the No! No! has a 2.1 overall rating out of 5 stars, yet on Amazon, the overall rating is 4.5 stars out of 5.
How many times have I been sitting there working late on the computer, and the No! No! infomercial came on the television? I'm thinking the number has to be up around 50, and they've put out more than one model of the No! No! as well. The video posted shows the No! No! in action.
