I don't know, as of now, I actually prefer the V1. The V2 is kinda weird. It's more stable, but it locks a lot on me and the corners are loose. I have it tensioned as tight as I can without being too tight, but the problem stays. I hear it rattle when I shake the cube, which doesn't happen on my V1. In a way it reminds me of the panshi.
I've actually gone back to the Weilong V2 for now, I'll have to get a new one because a corner piece broke. Or I'll get a new corner piece, I don't know.
