The Teraminx is a 7x7 megaminx puzzle which makes it an interesting challenge, if you can solve a 7x7 and a megaminx then you should have no issue solving the Teraminx, however, it will take a long time, the DianSheng Teraminx makes that solving experience more enjoyable as the puzzle has magnets allowing all the layers to align better, it also just has a better design in general so turns more smoothly anyway, I would highly recommend this teraminx over the other teraminxes on the market if you have the budget for it.
