The Exilis Elite is the newer, more powerful model. Despite all the fabulous marketing photos, my opinion is that there isn’t enough data in some of these areas to conclude much yet. There is more data on the face, neck and abdomen. If money is no object, then the worst thing that would happen is you would waste your money and time.
In my opinion, it’s better to wait about a year for more data to accumulate on effectiveness on some body areas – is it affected by age, weight, amount of sun damage, which treatment parameters are most effective, and how many treatments are optimal, etc.
