QiYi QiXing S2 Review | £11 non-magnetic 7x7x7 | speedcubing.org
The QiXing S2 is the best non-magnetic budget 7x7x7, it is not the same design as the spark as might be expected but has a pretty basic 7x7x7 design with little friction, if your budget is £11 then this is the cube for you but if you can afford to spend a bit more then get the YuFu V2M
