I just came across this post! If you are referring to the Jellen Portable High Frequency machine (not wand) I can tell you that it is very good. My esthetician recommended it to me a few years back. I use it 2-3 times per week and it still works great. I like it because it offers the same level of power as my professional treatments. I tried the Derma Wand but found the power level to be way too weak for me so I bought the Jellen system. It is the only thing that helps keep my acne under control! I've been super happy with it...
