I personally preferred the "original" old design. The button seemed a little smoother on those. I have no idea why they changed those to making you have to hold the button in while unplugging and plugging in again. Kind of a hassle (especially if you are dealing with a strap too.) But this does what the original circuit breaker cable did - allowing you to change guitars without having to turn down or have a "pop".  Just push the button in, let go and push it again when you are ready to go. I just don't like the push button as well as before, it's probably just me but this seems a little more cheaply made. I will still rate it a 4 though as they are pretty great to have and I would buy it again.
