I must preface this review by saying. This is my main, and I am biased towards this cube.
I will first off state. This puzzle will not fit everybody's turning style. I have the Maglev 20 magnet edition, and this cube is what I would describe as overwhelmingly fast out of the box. The layers auto allign VERY aggressively within 30 degrees of the apex and the cube seems to turn itself at times. I have not tried the spring version so I will not be mentioning it here, however I have heard claims that is is more controllable. I personally prefer a very light and fast cube so I do not regret my choice, but I can see this being a major turn off to a lot of cubers.
I am also going to mention a major issue with this puzzle. It likes to corner twist... a LOT. I have had PB averages ruined by this and it is the biggest fault of this puzzle. So please beware of this if you plan on using this cube at its lower tensions.
Overall. I love this cube, for 40 dollars you get a premium product that I find preforms better than current GAN cubes. The dual adjustment system is a very welcome addition as well and allows me to finally comfortably use a moyu cube without worrying about the evenness of my tensions or putting in hours of deliberate setup work. If you are looking for a fast and flexible cube the WRM 10 is definitely my top choice at the moment.
