After the great Gigaminx release from Diansheng, I was really excited for their Teraminx since I knew it would be good. The Teraminx does need some tensioning out of the box and it also needs to break in, after that the puzzle becomes really good. The only downside I could find is that I wish the magnets were stronger, although they do help with alignment I wish I could feel more of a magnetic pull with each turn I do. Another really good release from Diansheng, and now I can now wait for the Magnetic Petaminx.
