Teenage Engineering TX-6 Initial Button Defect. What!!!!!

I had the issue of TP-7 as the initial defect.
Again, TX-6 has the initial defect....
Come on.
TE has the great design and the music creation tool from their development.
But the production has the big issue to improve... Please, Please, please
I need the proper quality product for the music creation. I am no the QA engineer for TE. but if it is necessary, I am able to support TE as well.
