At first, it seemed cheap and not at all worth 75 bucks. But, I did beat my previous record on the Aofu WRM on my first solve... When it said "Triple Track has stability magnets" I thought they would be on the center corner where they always pop. Nope, they are just extra magnets on the edges that already have magnets. So, basically, the difference between this and the double track is stronger magnets. Oh well. I am still glad that I got the triple track, because the magnets are actually very weak. I wonder how weak the single track is! Ball core is an awesome color, and the cube is good over all. Warning, it is VERY small. Smaller than my 6x6 and 5x5. But, I suppose that it is fine. If you have the money, buy it.
