Taking into account that these cost 85$ (and a GMK base set will cost around 100-130) the quality could be better, a lot of keycaps (30-40%) have rough sides, needed to sand them gently, the legends are a bit blurry and the most annoying thing is they are deformed slightly on the sides. Plastic is thick though and colors are good. Cannot recommend this replica set unfortunately, not satisfied with the quality :(
Great quality for the price, the caps are the actual colors, not dye sublimated colors so they feel good. Thickness actually is very decent, on par with the better ones I use. There are some mold lines that need cleaning up, but for this price it’s an awesome buy!
