Ghosthand. I also found the exact same cube(without the logo) at a store in london when we were there for location. It was $5 and was called,"Professional magic cube"
I don't care what the OP says, my first speedcube was a Rubik's brand. I got sub-25 with it before getting an F-II, and I only got the F-II because a few pieces on the Rubik's brand were actually falling apart; otherwise I would have kept using the Rubik's.
My first cube is Rubik's. Then Rubik's DIY.
If you ignore rubik's brand, then i don't have any speedcube because i still use Rubik's DIY for more than a year an achieved sub 20 with it.
Only recently did I get my first real speedcube. A friend gave it to me and I don't even know what it is (she wasn't sure either). Looks like a type A but I'm not sure.
