This cube is really speedy and smooth and instantly became my main. It is very stable and shows no sign of popping or corner twisting. However after a 1000 solves or so, it became weirdly slower, and it seemed to be tighter, but if you put a little lube into it, it speeds it right back up again. Corner-cutting is line to line, and reverse is good as well. I definitely recommend this cube for intermediate cubers, or beginners who are looking for a faster option.
Overall, great cube!
