I have had this cube for about a month now, and it is a great cube. I had mine shipped with the pro set up and the lubicle black, and it was super fast out of the box. I originally ordered this as a back up to my Thunderclap V2 while I learned how to set up and lube a cube.

It has a very smooth feel, compared to my Thunderclap that is more clicky. The corner cutting is great, about 45+ degrees in both directions, and the caps stay put well, while they are still easy to remove to adjust tension. I have tried to change the tension on this cube, but couldn't get it any better with the stock system better than GAN could do. I only give this cube 4 out of 5 stars due to the proprietary tensioning system that I am not a fan of, and the stickers.

My issues with the stickers are that they are already chipping and that the blue/green contrast isn't my favorite. I would highly recommend checking out other stickers to put on this cube, and checking out the different tension springs/pieces for this cube if you don't like it right out of the box. The system that is on the cube right out of the box is a little loose for me, and when I tried to tighten the cube down a bit, it made it difficult to turn and still left the pieces a little loose for my taste.

I haven't had any issues with popping or corner twisting, but I have had a few lockups when I tried to tighten the cube. I could see this being a wonderful cube for folks that like to customize their cubes to perfection, but maybe not for those that aren't willing to customize and aren't used to a fairly loose and super fast cube as it can be a bit unruly if you aren't used to a cube like this.
