I know now what you mean with the 3 min setting showing easily on the skin... I stayed between .5 mA and .8 mA, yet the skin was red next day. I'll be more careful from now on.
Want to check this one out with you: There is a rather loud clicking sound coming from the box every time there is a currency reversal on all the Beck settings and the two Godzilla settings EXCEPT when on the 3 min setting, hardly any sound, even if I stay on the same .7 mA for all. Is this normal???
Thinking of buying a snow blower...
Thanks again
