The Galaxy V2M is my first and only Megaminx. With this puzzle I have progressed from averaging 3-4 minutes to now averaging 1:25 minutes, the equivalent of being 60th in India.
Out of the box it was very controllable, it seemed a bit small but that was simply because I was not used to it. Now I feel like my hands would seem unnatural on a larger megaminx. And what people say about smaller megaminxes reducing hand ache and tiredness is true. I can bust large sessions and still want to cube more.
I would recommend a fast setup as the cube is naturally controllable, smooth and a little blocky. Tensions are very important on this cube, do not make them really tight nor too loose, despite all that I think this is still a relatively easy cube to setup. :)
I would recommend it to anyone looking for one, perfect megaminx. But I have also heard that the Gan Megaminx is just as good but more slippery, so if you think a good grip is more beneficial to you, go for this one.
