A quick review about 2 new twisties: a pyramix by DaYan and a 2x2 rubik's by MoYu.
I find the it's nice to have a 2x2 cube this one is a good one: it turns smoothly and you can even use corner cutting, but I don't think this will be really useful though.
I am still trying to look for a good and easy to understand method to solve it. Not sure if there is a method to make the first step which is to make a side of one color (usually white). I did it randomly and must admit that it took me a bit of time.
Then is a stickerless pyramid. I have not yet tried to solve it, but I can say that it turns again smoothly and the pieces don't pop-up
I will need to scramble it and solve it now!
All what I can say is that the quality is very good to satisfy you and make your solving process a joy rather than a pain! ;-)
These twisties come from this online shop. They have plenty of choices!
