I was fascinated by this idea after picking up a dreadful one a year ago so I bought this, easily the best-value axis cube there is. Turning is so very smooth, I think the tensions are perfect, if you're serious about solving it I'd recommend putting in some slower lube but can't imagine anyone speedsolves this, it's more for the challenge. Very robust design, probably thanks to the torpedoes, I've noticed a lot of budget non-wca puzzles don't have them but they make this one very durable. Would highly recommend especially for the incredible price
