YJ cooked with this 4x4. Not only is it outstanding as a mini 4x4, but it is seriously viable as a main considering the entire 4x4 market. The corner cutting is superb and I find myself in very few lockups. As others mentioned, there is a slight popping issue but if you don't have a freakazoid turning style and focus on completing turns then you should be good. You can also just adjust the tensions if needs be. I have had a few "half-pops" where the pieces are still halfway in the cube and I can just smoosh them back in no worries. The size is the biggest factor for me. I have ever so slightly larger hands but this cube feels so natural to me and after using it for a while then going back to a standard sized 4x4, a standard size can feel almost unusable. The colors are amazing especially the green (I find myself staring at sometimes) so recognition is excellent. Overall, it's absolutely worth the buy, just be prepared to make it your new main. *wink*
