Because it feels similar to the GTS 3 M, and it's still a really nice cube. I have all the WR Ms and many more "new improved" cubes, but the valk is still my main.Why a valk? Isn't that cube... really old? A lot older than the GTS3M considering that it comes non-magnetic and magnetic.
Besides, it is 6 dollars more than the WRM. That is big difference in price.
