When they said Monster "Go", they meant it, because this things goes, and goes, and goes...very quickly...how quickly? I can do a U4 with the same amount of force I need to do a U2 on other cubes (this is after putting a ton of Weight 5 in there). The magnets are on the weak side and, due to the lack of adjustments, if I crank down the screws to try and tame the speed, the corner cutting suffers. Conversely, the corner cutting isn't that great on this cube and, if I adjust the tensions to get decent corner cutting, the cube feels unstable and uncontrollable.
The finish feels softer than MoYu's and is very nice to touch but gets very slippery very quickly.
At this price, I would recommend the MoYu RS3M 2020, unless you like really (and I mean really) fast cubes.
