Mine arrived yesterday, I've been exclusively stickerless for ages so I was looking forward to trying a modern Gan. It's the most aesthetically pleasing puzzle I've owned by a long-shot; shades, black internals, the subtle sculpt of the center caps... everything about it is beautiful with the singular complaint that logos are forbidden for blind (at least also provide a plain cap if you insist on making the the logo harder to remove).
I really want to love this puzzle but it's taking some experimenting to find a setup that suits me. Mine shipped with the green GES and I swapped them out for yellow almost immediately since it seems like everyone on Earth chooses those, from the reviews I've read. I couldn't really make the yellow work for me though. I either had to set it up too loose to be very stable for me with some finger tricks, or tighter, which was a lot more friction than I prefer and a little locky. I decided to try the blue ones on a whim last night, tightened a fair bit (maybe 2-3 threads exposed at the top of the nut) and it's far better for me but still not quite dialed-in.
Have you settled on a set-up?
