Im running the same mirrors. They work a little better than stock but look a lot better on the bike.Those look great, I'd consider picking up a pair. I can't see past my shoulder most of the time with the stock mirrors. Did the Koso set make a big difference in visibility?
Right given the ergos of the Grom probably no mirrors will ever be satisfactory unless you are four feet tall... they look great and match the Grom way better than stock.. but i still cant see past my shoulders.
