This unit is ideal for nano-pedal sized units that don't yet have a specific unit for them, like the Tone-City pedals. Unfortunately the silicone sticky-pad that it comes with doesn't do a great job of holding it firmly in place, so I suggest using 3M or Thomann pedal-board tape instead.
If I'm going to be picky, I would say that these don't hold quite as tightly to the board as I might like, and have a tendency to slide around in transport a little.
