I am selling the RadioPopper PX system. They are less then two years old. They work great. Never had a misfire. No problem with them at all. I used them with both Canon 580EX II flash as well as with the 430EX II flash. Normally on camera the Canon 550EX (which I am selling) flash is attached with the PX Transmitter controlling the Off Camera Flash (OCF)
Items For Sale: (ALL SOLD)
1 PX Transmitter & 1 PX Receiver – $330
1 PX Transmitter & 2 PX Receiver – $490
1 PX Receiver = $170
