Footswitch (Mod)

Does anyone have any opinions on the mod footswitch? Positive or negative…are there better Options?

I’ve had issues with the Duo losing connection with the footswitch.
Have to unplug and plug it back in to get Duo to recognize it.
Also would be nice to have a separate control for the display contrast.
Known issue: there is a timing issue when you switch boards where the footswitch times out.
Still waiting on fix.
