Hi Donnie
Not really, I am in great shape for an old guy. I need a mini key controller to use with my SD40 where I play from a table full of karaoke equipment, and space is tight. I need at least 49 keys and able to achieve a split. Full size keys makes to too long, and I can't find a 49 mini key controller. I need to control chords and lead sounds at about 18 inches.
