I just bought the gadget...tried it on my upper arms which I had lasered from a friend at 50% off...(they are now closed and I can't afford treatments.) With laser you need several treatments. I had it on my lower arms about 5 different times and it is alot better...not 100% gone but looks good. So I thought let me thin the upper arm...well only had 2 treatments and now they look worse then ever. Soo..I bought the no no to see if that will work..it is time consuming and doesn't give you a clean finish like a razer would...also feels like a shaved area growing in..not sure if I will keep it...don't want to shave the area so this might be ok to keep it somewhat hairless. I have had elctrol. on my face for years..my lip is done and I love it ...still get it on my face under chin and on sides a little..the lip was a painful process but so happy to have it under control now...tooo costly to do arms. not sure it I helped you but I thought if u just wanted an area somewhat cleaned up it might work for you...
