Bought this newer FC660M in silent reds to replace older model in non-silent reds. The new double-shot PBT keycaps are really nice. I had two previous FC660M's one with blank and one with printed keycaps. The printed caps were really poor quality and it's good to see them improve. I still swapped the blanks to this new board. Sitting side by side with a FC660C, personally I think they feel somewhat similar, although I actually prefer the silent MX switches. I wish Leopold would make anodized aluminum cases, my only complaint is that the plastic case on my older boards have started to show glossiness where it borders the space bar.

By far the best keyboard I've ever had. The key presses have the perfect amount of pressure and just enough sound on a key press. Also the feel of the keys has a slight texture that helps when typing for many hours. The look of the keyboard is also rad - very sturdy. I plan to get another one for work :)

Impressive build quality. No creaks or rattles. New doubleshot keycaps are great, as are the retooled cherry blacks.
