Pre owned . This device needs to be used consistently to see results . Depending on how many areas you wish to use it on obviously depends on how much time you need . Heads up , you’ll need to download app and pay for extra treatments. Although it does work independently from treatment programmes - which is how I used it , switch on and go. I’m too impatient and haven’t got the time . However, if you’re looking to buy one this may be a good opportunity to try one at a fraction of the price . I have used it a handful of times then discarded it in its box in a drawer. It’s in perfect condition although box is cracked from when I first opened it. Any questions please feel free to ask .
