I bought this cube for Christmas. Before that, I had a Rubik's Speedcube, so that was a huge step forward, haha.

I basically came from 45s average to ~24s with it in almost 1 year. I could've go even better if it didn't developed pop issue with time. It also became really slow, even with lube, it was back slow two or three days after I lubed it. The yellow shade doesn't really fit me either, but it was still really better than what I had before.

It's still a great cube with nice 45 corner cutting, pretty fast out of the box and really controllable, but time seems to make it become really slow. I first didn't have to tension or lube it, it was just great, but it felt pretty stiff after some time using it. Otherwise, it's a nice cube and still could be use to make really good times.

I could recommend it to pretty much everyone, it's a really good cube to begin SpeedCubing. Price is abordable, so go for it. That's a good product. =)
