Worth it if you're willing to put time into clock
Out of the box it is very fast and light, faster and lighter than literally any other clock out there. It'll probably be too uncontrollable for most solvers out of the box. I know it was for me, so I ended up tightening the screws until I was satisfied with the speed.
Also if you're coming from a different clock (shengshou or lingao), you'll find that you need to change your turning style a little to accomodate for the lightness, but this is remedied by doing about a hundred solves on it; the feel isn't too hard to get used to.
