Thanks for sharing your experience. I had an interesting conversation with another pulser manufacturer who said that the specs published by the Australian company were impossible electronically, as well as the number of pulses they claim. However, anything that works is good- and if it works for you, that's better than good.
Besides injury related pain, is there anything else you are using it for? Have you ever used any other type of machine? How were they different or the same? Something difficult about any critique of a machine is how to compare it to another machine!
