Moruska Qiyi 4x4 Speed Cube Stickerless 4x4x4 Magic Cube Puzzle Toy - Qi Qiyuan S

It's good quality not bad but not great, the colors are a bit too light though like it's hard to differentiate red and orange if you're not in good lighting

It’s fun if the 3x3 is too boring for you now. The cube is smooth and fast and isn’t too big. the instructions are not in english, but there’s lots of videos on the internet. Glad I bought this cube

This 4x4 cube has a very nice feel to it - moves easy but not loose, and for me it's a new challange, because unlike the 3x3 cube the center squares are floating and can go to the wrong sides; similarly the edge pieces can be permuted in ways impossible for a 3x3. Highly recommended. Has instructions in Chinese and English, for when you get stuck, which gives a rough outline on how to solve , and a few algorithms, but major steps are labelled "think hard". You can probably find a tutorial online if you can't figure it out and need it.

Turns smooth and well. Qiyi never fails.
