So far the machine has helped. However, I find the top 2 dials are so close together with that I can barely get my fingers on them. Also, I have yet to figure out how to do the minutes.
All in all, a good little machine.
What a great unit. Works great on my pain. Nice features too. I remember back in the day these were a$1000.00 and needed a prescription from a doctor. Very glad a bought this unit.
