I've had the first butterfly model (wast it 2016?), and indeed the keys would get stuck easily and I had to clean the keyboard with compressed air every other day, but even then I didn't have a single key broken down completely to stop functioning. And the 2018 model is much better, I will blow it with air occasionally, more as a precaution measure, and it works just fine.
