The XingHen TSM is an exciting new 2x2x2 from MoYu, it allows you to change the cubes size between 3 options: 50.0mm, 50.75mm and 51.5mm. It is a bit stiff out of the box but once you loosen the tensions and put a bit of fast lube in it, it speeds up significantly. It is nice and smooth with relatively strong magnets (probably 4x1 N50) but slightly lacking on the corner cutting. Unfortunately, it is only available in black so may not suit some people, hopefully this idea will be implemented into stickerless cubes soon though.
