I bought two of these so that I can control my old Nikon flashes with the X-PRO N trigger on my Nikon bodies. Works great. TTL and HSS work as advertised. However an additional benefit is that I can also fire my two Paul Buff Einstein flashes with these receivers. I now have four strobes (the Einsteins and two Strobepro AD600s) that can all be triggered from the X-PRO N. The Einsteins can only be fired - not controlled - with these receivers, but if I want to I can use my Buff Cyber Commander to remotely control the Einsteins. The X-PRO N and the Cyber Commander can be used on the same shoot without any problems. Another feature of this receiver is that it can be plugged in to a Nikon body, and the X-PRO N can be used to remotely fire the shutter release. I'm not sure how much I'll use this, but I tested it and it works fine. Cables are included for doing all the things discussed above.
Bottom line, I'm very happy with these receivers.
