The cube is my new main 3x3. Out of the box the cube was too fast for me, but after setup it's just awesome. The package arrived in 4 hours.
The cube is super, very light, smooth rotation, cuts corners everywhere. Out of the box a little dry, you need lubrication. My only complaint is that for some reason they used a dull red color in this cube, like on old Meilong. Other colors are the same as on RS3M, bright. The photo shows a comparison with RS3M. Delivery is very fast, less than two hours.
The cube is good, but you have to get used to it (the edges are easily punctured more than necessary - it is difficult to control). I recommend this seller.
Fast delivery. Item just as described. I will buy again from this seller.
