I love this cube and how speedy it is. It's just a bit too fast for me. The settings are great and the versatility of those settings are tremendous. I'm still trying to find the correct settings so it doesn't crash into itself while turning. With a 27.58PB and only 80% Alg memorization, I have a ways to go. Maybe I'll become fast enough for this cube to be a winner for me. Construction and design are typical of GAN. Love the feel of the cube. Weight is freaking amazing. It feels like I'm carrying a quarter around in my hand when practicing.
