Grind finish is excellent. Smoothness is right up there with any other yoyo in it's price range, which is to say it's very smooth. Thumb grinds are easy and lock in nicely due to the recessed thumb-grind lip.

Finger spins are not difficult but do require some skill and soft-finger technique. They do not lock in like a Shutter's fingerspin cup or the dimple on the Speedaholic XX, but the center of the yoyo is gently sloped inwards toward the axle hole which helps to center and "locate" the yoyo on your finger while it spins. If this was intentional then it's a very clever design.

The aggressive cuts of the cross-section look very cool and are effective at minimizing string friction, HOWEVER this is where the one caveat comes in. The innermost tapered cut of the yoyo is very shallow, almost parallel to the bearing surface as you can see in pictures. This causes a tactile "click" every time the yoyo is landed on the string, since the string rides on that cut for a few thousandths of a second before dropping into the bearing gap.

I'm not a fast player so I enjoy the clicky landings, it gives the yoyo a unique character. but if extreme speed is your style it could theoretically slow you down. I've not noticed any drawbacks of the click personally. No accelerated string wear. I've been using Alphaline on this throw.

The axle is 8mm and is pretty short, the yoyo will fit a 9mm but not 10mm.

In summary, I'm pleased with this yoyo and consider it well-priced in the $60 range.
