Pros and Cons
Pros:<br />More powerful than the cheap Chinese TENS/EMS machines.  I couldn't get any of these to cause a tetanic quad contraction even turned all the way up.  No problem doing that with the Compex.<br />4 channels rather than the usual 2.<br /><br />Cons:<br />They have engineered the cable end to mate only with Compex brand electrode snaps.  Their brand is no better than the generics but is 4 times more expensive.  In order to use the generic electrodes, you would have to grind down the tit in the inside of the cable button with a Dremel tool.  If you do be careful because they charge more than half the cost of a new machine just to buy one replacement cable.<br />There is no way to program the device.  You are stuck with their programs and can't change any of the parameters manually.
