I bought a Kaoss Pad 3 shortly after getting my OT but sold it a few months later.

It was a fun bit of kit but it was way too noisy compared to the rest of my setup. I don’t know whether I had a dodgy one or whether I was being fussy but it seemed to put out a constant low level hiss.

Either way, sold it and bought an MPD32 and I’ve got much more mileage out of that than the KP3.
