Can the device setting such be adjusted or are the programs fully set? I want to be able to adjust the wavelength, HZ and intensity levels.

you can only adjust the intensity levels. There are many options available however on the device for Tens and NMES. works well

How many electrodes come with uthis unit?

8 electrodes come with the unit, which has been a sufficient number for me. I have used the unit continuously for the past 3 months and just started to use my last 2 electrodes. But I have also just realized that to rejuvenate their stickiness, all you have to do is wipe the patches periodically with a damp washcloth and it restores their stickiness! I'm so thrilled with this unit! It really has helped me! And I hope my review helps you and others.

Seller Please tell what are the items included in this package?

I am a purchaser, not a seller. But the item includes the power unit, cord leads and one set of pad leads,

what is the maximum pulse width?

Like 50, you wouldn’t want it any stronger!
