I'm extremely skeptical that there are differences between units. I suspect it's purely down to individual variation how people press keys. When I got my 15C CE, I worked through all the examples in the Owner's Manual for the first time in decades and those in the Advanced Functions Handbook for the first time ever, and I had barely any problem with key bounce. Probably because I pressed the keys very deliberately. Now that I'm using the CE casually, I run into double key presses too often. (Firmware 2023-01-05.) But as soon as I start paying attention to it, the problem goes away again.

Sadly I couldn't make the time to visit IFA and get some hands-on feel at the SwissMicros booth for the handling of their calculators.
