This was my upgrade from a generic USB-C cable to a coiled aviator cable, and it's fantastic! The colors are accurate to the photo, very pretty deep blues. It matches my Portal-themed board very well. Shipping to the US took 14 days, very fast! I did not get any automatic shipping updates, but my order email did have a shipping number to track. Packaging was great, bubble wrap taped around the box holding the cables. The cables are in separate colored boxes, so if you only need one half you'll know which one it is immediately. Very sturdy cardboard, well-protected without being excessive.
The cables feel very sturdy and flexible. The only negative is that there are slight bends on the straight sections of the light blue coiled cable, but this is very minor and likely because it is brand new. Not a permanent issue at all. I will definitely come back to Yunzii for my next keyboard cable!!
