The Dayan Zhanchi is one of the best speedcube on the market. It was released in Early 2011. The Dayan Zhanchi comes in Black, White, Red, Green, Blue, Yellow,Primary, Purple and Orange. Feliks Zemdegs broke the Fprmer World Record Single of 5.66 seconds using the Dayan Zhanchi.
The Dayan Zhanchi is a fast and smooth cube but has a snappy feel. If you want to slow it down, be sure to add some lube to the pieces but do not overlube! Corner cutting is 45 degrees with proper tension. Reverse cutting is also line to line. Pops are not a problem as it has ‘torpedoes’ installed into the cube. Lockups can happen sometimes but is not a problem. Overall the Dayan Zhanchi is perfect for anyone who is looking into upgrading to a better cube. It is recommend for cubers who are fairly experienced in cubing.
