Having been recommended the V1 of the Dayan Tengyun by a friend, I was keen to give it a try.
The Tengyun V1 has a reputation for being one of the quiestest 3x3s on the market and it certainly lives up to that.
However, out of the box this cube is rediculously fast and uncontrollable. After setting it up with Angstrom Gravatis and Dignitas and adjusting the tensions as tightly as I am comfortable with, it's still way too fast for my tastes and I struggle to control it. This has also reduced the corner cutting capabilities of the puzzle.
Another thing to mention is that the magnets installed in the cube are very light, almost to the point where you can't feel them at all. My hope was to add extra magnets into the edges much like I have done with my WRM 2020, but the caps on the edges are on very tightly and I don't want to risk breaking them trying to get them off.
The Tengyun V1 is not for me but if you like an incredibly fast, quiet 3x3 with very light magnets, it may well be for you.
Service from KewbzUK remains as stellar as always :)
