loses adhesiveness too quickly
As a user of TENS units for quite a while now, I have used a number of pads types and manufacturers.  These are ok, but the adhesive layer is very thin and tends to peel up on the sides.  I have found that the bulkier ones tend to stick along their entire surface (thus relieving the sharp pain associated with the loss of skin contact-----if you have used tens units with dry pads, you know what I am talking about).... For the price, you could probably use them as disposable units, but I prefer to pay a bit more for pads that hold their adhesiveness better.
