The metal rims on it spin freely from the plastic. Bad quality.

Good powerful yoyo, Im confused though
4 is IV not IIII, also 6 is VI not IV
Just an error or is there a deeper meaning?
Also I love the sound of it

I really enjoyed this yoyo as I was practicing in my living room, but when I brought it outside I found out it is unusable. When the temp is below 50f or 18c the rims slide on the plastic. Basically turns the weight rings into hubstacks. This ruins the momentum and makes it unplayable. I guess this is just a climate control or summer daytime yoyo. Can't be used at night when temps get low. Contacted mowl and got the run around. This is a $90 waste of my time. Also it has special shims only available from mowl that fly out of the yoyo really easily. No extras included so be careful when taking apart.

I've tried a number of plastic and steel, bi-material throws. This is absolutely a knock-out throw. Incredibly stable and fast, finger grinds are A+ and it even has a very nice inner ring for thumb and talon grinds. If you are a fan of H shaped yoyos, this is probably one of the best you can find. The bearing that comes with (DifeYo concave style) is extremely high quality. This gets a phenomenal spin time even on a weak throw. MOWL is a great company and Eiji has a very keen eye for design. You will not be disappointed in the Surveil.
