Buttoncaps for Podium Button Module Endurance?

I bought the Podium Button Module Endurance 4-5 years ago. The device itself is awesome.

However the button caps are horrible. I have no words for it to describe how bad they are. I can't believe they passed quality control.

with a simple button press they crack. and eventually totally break. At the time i contacted support. They sended me the exact amount of broken caps instead of sending me atleast a full set. Before i recieved the new ones, others broke. and eventually also the new ones.

i didn't play for 5 years so i didn't bother anymore. But now i don't want to spend a lot of money +30€ delivery costs for some cheap chinese plastic that will only last some weeks....(best case scenario)

Does somebody had a similar experience and does know the quality infact improved over the years? i don't want to be scammed twice or do you know some good alternative button caps?
