This cube is fantastic. It moves so well right out of the box. A friend tried it out and described it as "This thing just wants to fall into the shape of a cube" and he's totally right. The corner-cutting is great. I've only seen it lock up when I'm being really sloppy with my turns, which is understandable because I know I should continue cleaning up my precision if I want to crunch my solve time a bit.

I lubed it up with Lubicle Weight 2 and after breaking it in it moves even better. I might try another lubricant soon because I just ordered the premium lube kit. If I notice major differences I'll come back to update with what I did.

All in all, I highly recommend this cube as a great 5x5 speed cube to start with. I'm able to focus on learning the algorithms while practicing precision with my finger tricks. Before this cube I had a Meffert's tiled 5x5 which was big, slow, and clunky (and popped a lot). It use to take me 10 - 20 minutes to solve. I was immediately able to solve this one in 5 - 7 minutes. It feels sturdy, is easy to move and practice on, holds lube well, and is an all-around great cube to have as your 5x5 main.
