I have KORG Pitchblack PB-01 but it is a full size pedal and take space, but this new Korg Pitchblack X MINI is unbelievably small, it does the job well, however I wish it would have the old Pitchblack display mode, this is probably why I keep them both big one for home and small one for pedal-board hehe. Overall no brainier to buy, great tuner, definitely recommended.
