I got this at DFW Cubing Fiesta June 2018 from Cubedepot, and I did a few solves and put the ball bearings in before deciding this was my new main. I love the feeling, the sound is awesome, the speed is great, and I love everything. I used Traxxas 50k, wiped it out, and then I loved it even more. I lost one ball bearing, but it was not a puzzle defect. It just happened to me because i dropped a piece that was apart. Overall, I'd highly recommend this 3x3.
