First, the name of the item as it's listed on the website should be fixed. The FC-WR is the Commander, not the Receiver (I also have the FR-WR Receiver). The name is shown correctly in the manual. Anyway, I went back and forth as to whether to buy the FC-WR versus just getting another FL-700WR since the FL-700WR has all the same functionality as the FC-WR and only costs $10 more. And the FL-700WR has a flash and focus-assist light, which the FC-WR lack. So far my flash configurations have been either on-camera or off-camera, but not both at the same time, so I didn't really need another FL-700WR. The FC-WR is a good fit for my off-camera-flash shooting. The FC-WR was easy to set up and get it to work with my FL-700WR units and my FL-900R (with FR-WR Receiver). I like how the FC-WR is significantly lighter than the FL-700WR, and I also like the dedicated group buttons on the FC-WR. They make it a bit more convenient to change settings. I also like the simpler interface with the FC-WR that only covers the necessary commander functions. Overall, this was a good purchase.
