Here is the one I have and love it. As you can see it does multiple things to include MN RF Fractional, HIFU Vaginal Tightening, 4D HiFu, Body Slimming and Vmax. I love the 1st two items and use them all the time. I need to stay on a schedule with all of them for real. When you have all the toys it's hard to focus on just one. I usually always buy the biggest and hopefully the best but with the way technology changes so quickly maybe buy the individual unit you really like because I feel like I have left money sitting on the shelf and haven't been able to fully use what I have. Yes, I do use the RF MN all over the body. I used to be a pretty active athlete and now that I am 57 I don't like the way I looked in dresses any longer because of the flabby skin over my knees. Well I am back to wearing my shorts and loving my legs again. Doing some squats would help but seems like I can't find the time. I will do a better job for sure of getting some physical fitness back in my life. I hope this helps you with your choice.
