If anyone has any feedback on this I would like to hear it.
I remember seeing one of these years ago, it was a third-party add-on product with pitch-bend and modulations wheels in a little portable 5 inch plastic box, which was connected using standard MIDI ports.
Basically the idea never caught on, for a number of reasons - if there was still demand for these products, companies might be making them today.
With a loose portable add-on device, as you physically push the wheels, the lightweight box keeps sliding around all over the place, unless you can stick it down to the keyboard with Velcro or gaffer tape.
You might think people with a domestic digital piano with 88 weighted keys but no pitch / mod wheels would be a target market, but even if you could send MIDI pitch-bend and mod control data into this digital piano, the instrument may not be designed to recognize and respond to it, and won't have any user-programmable facility on-board to offer assignable MIDI controller parameters anyway, so the wheels are useless for that digital piano anyway.
For a synth keyboard however, if it is designed and built to recognize and perform with pitch / mod data, chances are it will already have its own wheels built-in already.
The only real use is for taking MIDI output from a nice 88 note digital piano, going Thru a pitch/mod wheel add-on, to merge the MIDI out data, and feed In to a synth rack module or computer software that can use pitch / mod data. However, there are so many other useful control parameters you could have handy as well, so most companies these days offer universal MIDI controllers with many assignable knobs, sliders, and buttons, rather than just pitch/mod.
But there are devices like this you could buy...
The top one, Kenton KillaMix Mini
has an X-Y joystick that could be used for pitch / mod plus 9 assignable knobs and buttons, but uses USB rather than MIDI.
