I purchased this because I tore the tendons and ligaments in my fingers, tore the nerves in my wrist and arm, and 2 tendons in the wrist. After surgery I had severe nerve pain from the damage. My doctors and therapist told me to get a tens unit for home use. I looked at just about every website and tens unit out there. I decided on this one because of several reasons, the cost for the product was perfect, the programs were what I needed in all aspects, and it came with everything I needed. I do recommend getting the rechargeable 9 volt batteries and the rechargeable charger to save time and money in the long run. So back to this, I used the tens most of the time and have it programmed to what I can tolerate to help with pain. I use the EMS when I need to do resistance to try to get flexion back in the fingers and wrist. So overall, buy this and you will be happy.
