Opening the 3x3 category this cube is the cheapest but one of the best speed cubes you can find. A lot of fast cubers love it and some of them use it as their main (me too even though I am not that fast). For $9 it does not provide magnet customization, but that is different about the springs settings - in the box you will find a little tool that you can use to change the core settings.
The newest cube from DaYan’s legendary GuHong series. It does not provide any customization but is still a pretty light, good, and fast cube.
Back in 2018 QiYi’s X-Man designs released their first 3x3 speed cube - the Tornado. And now, in 2021 it is back with the Tornado V2 M. A lot of people describe its feeling as very similar to the GAN cubes, but the cube is way cheaper than one. The cube provides two types of core adjustment and five magnet settings. The cube is also slightly smaller than most of the cubes on the market (55mm).
The second version of one of DaYan’s best line of cubes - the TengYun. The first one was known for its quietness and that a lot of people still use it as their 3x3 blind main. The cube provides springs and magnets customization.
May look weird that this cube is here even though a lot of newer versions of it came out, but that cube should not be missed. It does not have customizable magnets but has customizable spring settings (MoYu’s standard springs adjustment). The cube is prefered by many of the best speedcubers - Tymon Kolasinski, Patrick Ponce, Lucas Etter, Luke Garrett, and more.
Here the most expensive cube is - the famous 11 M Pro by GAN. It is the first puzzle that provides the revolutionary core-corner magnet system by GAN. Of course, the cube has the normal edge-corner magnets too, which are adjustable (the core-corner ones are too). You can also change the cube’s springs strength with the fancy new GES technology. It is the main cube of one of the best speedcubers in the world - Feliks Zemdegs
