This is a fantastic Cube. I have been speed cubing for about 10 years and average about 15 seconds. I own 15 cubes from top brands and this one is now my main. My previous main was a Gan 12. Out of the Box, the Tornado V4 felt off and I could never get it adjusted quite right. I had all the dials at 1 and it still felt like it was too tight and i had the corner magnets maxed out and it still felt like I had no control. Luckily this cube aged incredibly. after a few hundred solves, it loosened up and is now my favorite by far. I was eventually able to control it well enough to dial back the corner magnets to a more comfortable setting. Now It is much faster than the Gan 12 and I have less lockups on it. I use the Martian lube with it as needed and that makes it even better. Overall this is a great cube. You wont regret this purchase, just give it a little time to break in.
