I sure did! Big updates coming out for it this week, too 
A separate note---my coworker has the RGBW Zigbee controller and he likes it a lot. I'd considered getting one, but the updates to my driver that I'll be rolling out really bumped up the performance on them, and I think I'll stick with what I've got. Don't let that stop you from getting the Zigbee set, though! They're great, too.
Edit: Something I'm unsure of: Does the Zigbee RGB/CCT controller let you have all 5 channels on at once? Or does it force you into RGB mode/CCT mode? That's a pretty big feature for me that might impact some users.
