This is my first time ordering a puzzle from Daily Puzzle, the parcel arrived quickly just a few days after my order. Shadow M 6x6 is very light in weight despite having the magnets and has a unique sandy and crispy feel out of the box. However, it does lock up or pop when turning inaccurately, this can be resolve by tightening up the cube. I previously owned a Qiyi Wuhua V2 and my time has dropped significantly after receiving this cube. I also own a Aoshi GTSM 6X6 which is also a great cube with less lock up and pops, but it is slightly heavier than the Shadow M.
Overall, I am very happy about the performance of Shadow M and I would recommend it to anyone who wish to get a new 6X6.
