Yes, I am using it for the first time. One of the issues I had initially was understanding the different modes and levels of intensity. The standard red light therapy units have three modes: 1) regular 2) 10hz pulse 3) 40hz pulse. It didn't explain which one to use for my specific symptom(s). I had the same problem with the 5 intensity levels. I researched these questions on line and got some answers. Bear in mind this is not a quick fix but a long term treatment program. I just started using the device this week so I can't draw any conclusions except for healing some skin damage I had on my big toe. It really helped with that problem expediting the healing. My unit is for feet and ankle areas only which is my affected area for PN. I also use a device called Neurogo which provides electrical impulses to the feet, ankles, calves and thighs to stimulate blood flow. You can feel it working but it is also a long term "solution". The jury's still out for both of these devices since I'm just a newbie. I will post progress reports periodically.
