Compass health brands of middleburg, oh makes a tens 7000 rechargeable medical device (item dt7303).The on/off button and start/stop button are one single button and that button frequently malfunctions leaving the unit either stuck in on or off mode with no way to alter it until the battery on the unit dies.I have experienced this multiple times.It is problematic when it is stuck in the off mode because then i can't use the device for many hours for treatment.It is more problematic when it is stuck in the on mode because i then have to remove the tens electrodes mid-usage which is painful and i fear it could be dangerous to me and to the unit.Pressing and holding the button normally shuts the device down, but often results in the screen going blank, but the backlight remaining on.At this point, none of the controls seem to have any effect on the unit, although it will still beep (what the beep signifies is not known, because the unit doesn't seem to act any differently).
