gitsh01Hi gitsh01, thank you for your rating. Because this product is machined all 5 surfaces from the most basic step, the top surface will not be exactly the same as SA R1 (which is a differentiating process). So they have some unique characteristics.
I got this for my girlfriends keyboard, but I was really tempted to keep it for myself after I saw it in person. The keycap is well crafted and very beautiful. Would highly recommend it to anyone interested or on the fence about it :D
