Obviously this is expensive but if you want a gigaminx and can afford it, then highly recommended. The magnetisation really helps and makes it sweet compared to the non magnetic ones.
I've also got the YuXin Gigaminx which is also very good and 2/3 the price, but the lack of magnets really means you have to worry all the time about previous moves. Unless you were super precise the next move might not work.
Also a fairly small but noticeable plus point, the much wider central edge pieces make finding a lot easier than on the YuXin.
One minor negative. I find the white and the cream/ivory to be annoyingly similar in colour. It can be hard to tell them apart except in amazing light.
Summary: I can imagine a better gigaminx but for now this is the best there is.
Disclaimer, not a speed cuber at all, happy to do the gigaminx in an hour.
