This is the Dayan 2+ (torpedoes)

A very, very fast and smooth marching cubes. The cube voltage is adjusted quite well from the outset, the screws, which are located under the covers of the middle plate, must therefore in my opinion not really eased, but are processed only with silicone spray (so you no longer grind the springs hears).

Generally, the cube is "unlubricated" delivered so that a comprehensive treatment with silicone spray or silicone oil (do not machine oil or WD40-silicone spray !!!) is even more necessary. This is quite normal and after lubricating the cube runs faster and rounder than any other speed cubes that I held so far in my hands.

I like it much better than the 5 Dayan, with my knowledge of the current world record was set, but that's basically just a matter of taste anyway.

Features:
-Click very little, is quiet and very smooth (and not "crispy") even during fast cubes

-Runs really unbelievably fast when he was treated with silicone

-voltage Of the cube is set well right from the start

-has of innnen built "torpedo parts" that hold the cube well and unintentional Poppen (jump out of the individual cube pieces) during fast cubes reliably prevent

-verhakt despite the torpedoes did not (have not done, at least until now this experience with the dice)

-Needs no sticker and has a very pleasant smooth surface

-is very easily and acts for Inexperienced "Zauberwürfler" therefore first like a cheap product, although it is not entirely.

Very strong buy recommendation for people looking for a very fast SpeedCube.
