This product may be fine but it does NOT fit the Omron Pain Relief ...
I purchased these to fit the Omron Pain Relief Pro PM 3031.  They do NOT fit the Omron PM 3031, in fact I can't find any electrode wires that do.  I spoke to an Omron representative who told me that electrode wires are not available for the PM 3031. This product may be fine but it does NOT fit the Omron Pain Relief Pro PM3031, please don't buy it for that.
