That price difference between Softpulse and Actipatch is well known and has been reported here for years. Years, as both were selling to the public. Still the sales of Actipatch have been weak. Don't know what the sales are of the Softpulse, but the sales of Actipatch have never been enough to make Bioelectronics profitable. So it looks like the price difference between the two is irrelevant and no advantage for the sales of this never profitable family run corporation.
