Longer lasting, superior, and less expensive than some more popular products.
Work great!  I had only used Empi products in the past but I think these are superior to that product.  I have very dry skin and the Empi had to be discarded at a higher rate than these.  You can only clean them so many times before they are ineffective and I have found that the Tyco electrodes tolerated the reapplications at a longer rate.  I highly recommend this product.
