Had I been a member of this forum when you got that fork I could have saved you a year and four months of time.

Spinner proved to be very unreliable and customer service is non-existent in North America. ...
Yeah, but what fun would that have been? lol
That info was pretty much already out there, at least about the customer service. However, my experiment was something completely different. I set out to answer the question, "Is the fork any good?"
It was cheap enough to purchase just for the sake of an experiment. ...
Let the fun begin.
My experiment generally supports what you said, though: The quality control sucks. Only half of the forks we ultimately received actually worked -- even when brand new. One of them wasn't even the right travel length. That suggests poor manufacturing, design, and marketing. Additionally, the fork's progressivity felt dead. No combination of rebound and pre-load made it plush. Rebound control sucked. When I get some free time I'm going to dig one of them out of the cobwebs and tear it apart to see how awful the mechanism is.
On the other hand, the forks were extremely light, durable, and stiff (as in not flexy or clunky). As a pure "shock absorber," it was fine. But as a suspension component, I was unimpressed. Unfortunately, the shock just didn't feel good for any price point. So the Fox went back on my Racer-X
FWIW, my next bike will be a FS 29er, and although I'm a Fox lover, I'm almost certain that I'll be going with DT Swiss's carbon fork.
