This Tens unit, has a much smaller controller. It looks a lot like one of my old cell phones. It fits in my hand well and doesn't cause me any pain. I like that even though it is small, the screen is a great size and you can read from it with ease.
Basically this comes with electrodes. You place them on your body in the area that you want massaged. Then you just turn on the unit to the point that you want it and it will give you an amazing massage. I have used this all over my body and I can tell you as someone with Fibromyalgia, it really does help!
One other thing I need to mention, is the box. It looks like a normal box, but it is actually really cool. There is a magnet in it to keep it closed and it is made well, not like a usual cardboard box. It looks great stored in the box, so I am going to store it in there from now on!
This is an amazing unit that will give you a great massage, I am so glad that I got to try it! You really need to check it out on the Santamedical 180 Tens Unit product page on Amazon. From there you can find out more about this product, see what other people are saying about it, and you can pick one up for yourself!
