Of all the cubes that I have had this one is the hardest by far at the beginning when we start to manipulate have the impression that it will explode our fingers but made one quickly takes the raids. Beware if you do not ensure all slices stacked properly, it may be that a piece is dismantled (hence the 4 **** for resistance) but the 7 v cube 7x7x7 cube is the best I can highly recommend this cube is really EXCELLENT !!!!!! Very good challenge for lovers or cube amateurs of all kinds. good luck and good luck !!!!! .....
