Stable and fast
This turned out to be awesome for mycase, infact more smooth & magnetic than x-man 6x6M. It is smooth, on top of it I like x-man cubes as strong & sturdy. Used a 6x6 MGC cube earlier for few days which use to pop frequently. This x-man is smooth & reliable. Magnets are stronger inside & lighter on outer layers.
The X-man spark is a great cube out of the box. It turns very smoothly and fluidly. I have had no pops or lock ups since I have purchased the product. It can corner cut but you shouldn't try to purposely corner cut
