The QiYi Thunderclap 3x3 is the latest cube in QiYi's MoFangGe series. The mechanism appears to be an improved version of the QiYi Bullfight. Out of the box, it turns smoothly and has a clacky feeling. It comes in a large box with a high-quality mesh cube bag. It is pretty scratchy right out of the box, but after about 15-20 solves (for me at least) the cube is smoother and turns way better. Adding dnm - 37 makes the cube way faster. I haven't added magnets yet but I am looking forward to doing that. Plus the mesh bag is a very nice. I would rate this cube 10/10 and would recommend it to any beginner/intermediate solvers. Over all the turning and corner-cutting of this cube is really close to professional cubes.(as far as I know.) I was super excited when my Thunderclap came in the mail. When I opened up the box I was happy to see the cube and a little black bag to hold to my cube in, but sadly the string to close the bag broke in about 2 weeks.
