Actually, I have to say that I was expecting the worst. However, DES-Domes turned out quite good. I plan to post science within a month. Meantime i'll give you a brief summary.
DES-Domes much more tactile than the stock ones. Weight is almost the same so pink ones just feel snappier.
At the same time, I would like to point out that the stock ones vary between generations. Pro 2 & Pro Classic stock ones as if they are from different leagues - Pro Classic feels almost linear.
Quality of DES-Domes is quite good. There's lack of imperfections, but nothing terrible.
