Bonjour from France !
:not too small for speedcubing, and great colors like the original cube of the 80's. Loud and strong plastic as usual by Dayan, but:
-:it's a Dayan Guhong, but my old guhong from 2011 is really better. This one is clicky, a little bit scratchy, and sometimes stop during the solve...
Edges had an unsual shape that could explain stoping.
Conclusion: best look, medium for solving,and you 'll really find best smoothy 50 mm cube in another famous brand stickerless.

Great cube

Smaller, than I expected, but I love it. Can't put it down!

This is a great little cube, turns great and is the right size for either small hands or for solving one-handed. My only problem is that the corners can be a bit sharp due to flashing, but I'm sure this could be sorted with a small amount of sanding.
Overall, I love this cube! :)
