I highly recommend you actually buy an ICES PEMF unit, you use it, you share your personal experiences.
Good morning!
I am wondering if i should be able use the coil tester on the hat? It does not light up when the hat is turned on.
Disregard. Question answered above! Thanks 
Regarding the treatment duration: The StimuField website says: “For best results, we recommend using the StimuField PEMF Cap daily, with each session lasting 30 minutes. Exceeding the recommended frequency or time will not enhance the cap’s effectiveness. Please do not exceed the recommended usage.”
I already have a PEMF mat, that I use daily for 10-12 hours at 25 gauss. It has square waves and a fast slew rate according to the manufacturer. The manufacturer recommends 20 minutes daily for the mat but also says that there is no harm in using it as long as you want.
I also have a red light therapy helmet and a Niostem helmet. I don’t use those every day because the red light can cause shedding and for the Niostem I’m too lazy sometimes.
Is it OK to add the cap to my routine? Can I use the mat, one of the two helmets and the cap (for 30 minutes) daily or only a subset of those? How much time should those treatments be apart?
Could the cap give better results when used twice daily, e.g. in the morning and evening? Are the recommended 30 minutes simply because that’s how the study was done, or can it be actually bad if used more than that? I don’t notice anything bad (or good) from using my mat for hours. In the past I also used it only for the recommended 20 minutes daily, but it made no difference.
