Pain Relief, But is it Harmful?
As far as pain relief, this pad deserves five stars. But the instruction sheet is incomprehensible. Here's instruction No. 1 exactly as written: &#34;1. Electromagnetic wave shielding knob: Used to eliminate harmful electromagnetic wave, when the hand contact knob, removal of electromagnetic wave, the indicating light is bright, the left and right in either direction of rotation of the knob, the removal of the electromagnetic wave indicator, if not out to reverse rotation can be.&#34;<br /><br />Not wanting to absorb &#34;harmful electromagnetic radiation&#34; I phoned the company's Customer Service to clarify the instructions, but the  rep's heavy accent and poor English did not fully answer my question. So only one star for the instructions versus a possible five stars for the product. I'm still not certain how I can avoid &#34;harmful electromagnetic waves.&#34;
