Just bumping to give a quick review by someone other than the manufacturer.
Size: Same as the type A-V, (so slightly smaller than the average cube) however, this cube feels tiny, and I really like it.
Weight: Slightly heavier than the A-V, but very close to the Guhong (too close to call)
^ sections were just how they feel/look. I didn't actually weigh them on a scale.
Feel: I've only had it for few hours, but it reminds me a lot of the "Haiyan Haiyan" cube (wrongly named I'd say

)
It's very fast, and has a smooth, and weightless feel.
Characteristics: As I said, very fast. It has decent corner cutting (right on one cubie at the current tensions) and hasn't popped on me yet. It reverse corner cuts a tiny bit too. I'm sure if I could control the speed a bit better, it wouldn't lock up. If this cube was white (I received a black one to try) I would consider it for my main speedcube. I particularly like it's potential for an OH cube. I've had some good times. I had some info on the mech, but when I opened the thread, I saw it had pictures.
It's a good cube, and I recommend it if you are partial to the "Haiyan Haiyan" cube, and also if you are looking for a nice OH cube. I would rank it number 1, but it's up there.
