From Maugee to you,
If the name of this TENS unit twigs your memory? You may be familiar with the original Eclipse TENS unit. Unfortunately, this isn't it. This unit is digital and the original was analog etc. etc.. The wires from this unit will not fit an original eclipse TENS unit.
We have replacement wires and batteries for the original eclipse TENS unit. You won't have to retire that great old TENS unit.
