This 4 by 4 is really good and worth buying it has a fast and sleak movement out of the box it was dry but after lubricating and breaking in it was really good I recommend to save some money and spend on wuque rather than this

The 4 x 4 turns very smoothly. Works great and great price. Customer service with these guys is wonderful! Would definitely recommend!

It worked pretty well

Much better than my last 4x4. It's inexpensive and worked flawlessly for me. I'm sure there are better options out. But I'm happy with the puzzle I had received. Well worth the $12 I paid.

It actually pretty good. I didn't know what to expect as it was a little cheap.

This cube is really great out of the box. It's pretty fast but tends to lock up a little bit. It's very cheap and I recommend that you should try it out if you average times that are 50 seconds or longer.

Great 4x4 for amateurs and experienced cubers
