Lacking in a couple of areas. Love the ability to reorder my pedals. I didn't think I would use it as much as I do. Extremely flexible in routing/midi control capability. One of the biggest problems is that when you switch from to manual mode to turn pedals off and on and switch back to preset mode it reloads the preset (turning off your previous changes in manual mode). Also no usb port for updates so if they decide to fix this will have to be done by midi. All in all it's a pretty awesome switcher!
