No surprise to me but it works just fine.
I paired the ZWave Fan Controller and then plugged in a Lasko desktop fan:
I set it to high on its selector on top of the fan and plugged it into my cobbled together outlet. Using the Device Info page, I was able to choose fan speed and indeed, the fan did those speeds. I believe the GE only does High, Med, and Low so the med-low and med-high options on the page seemed to only pick Medium as expected.
Low is a very gentle breeze via the GE. The Fan's physical 4 position switch isn't as gentle. In fact, the first time I clicked Low on the Device Info page, I thought the fan had shut off. It's still spinning on Low 5 mins later so it's definitely low. 
Now I have to go to Lowes/Home Depot and get a nice looking box for this
