The Xman Spark is truly an outstanding 7x7, it's fast and silky smooth while retaining an immensely stable body. The Spark has nice shades which makes recognition easy, its magnet strength it's really nice having medium magnets on the outers and strong magnets on the second layer and extremely strong magnets on its inner most layer. The Spark is really fun to use, it's smaller size makes holding it and turning quickly really easy (especially because of my tiny hands). OOTB the Spark was quite lubey (not to the point of a dayan cube) and scratchy but after 10 solves the cube breaks in and it starts feeling great. All I did to set it up was a couple drops of DNM and silk and I tightened the screws by a quarter turn. Overall I would recommend you get this cube it's one of if not the best 7x7 out there and for 82 bucks you get what you pay for the only negative I can see is it is a bit slow OOTB. Shipping as always was extremely quick taking 1 and a half days which is crazy. Thanks speedcube.
