If you are using a TENS for low back therapy - buy the belt.  It will save your skin and definitely aggravation!
First off, it works.  Buying online, I was a bit concerned.  But it works fine.  I've used a TENS device before by prescription and I had to apply the electrodes.  Which was a pain in the arse if you have to do it yourself...think contortionist...MUCH easier to just put on the belt (using a bit of the electrode get).<br />This device delivers very gentle to a bit more deep therapy.  I have severe low back pain, L4 and L5.  Given my experience some years ago using a TENS and electrode placement--I decided this device was an absolute necessity to go along with my new TENS device.  There's no way you want to have to apply the electrodes every time you have to treat your back.  This is easy-peasy.  Just remember to use the electrode gel and give yourself a chance to get used to wearing the belt.  First out of the gate it will seem a bit awkward to place it just right.  Experiment--and get some great relief.  I have also used this when out on a long hike (7+ miles) - I knew I would get sore so I brought it along.  Rather than taking the meds to get through the rest of the hike, I used this.  Very pleased.
