This thing replaced my original PocketWizard set which cost about $400 20 years ago. Absolutely reliable, light, compact. Mine just broke after a day of use. There is no signal at the PC connection of the receiver. After a few letters I received a full refund of the purchase price. I bought another one with this money, it works fine. I then disassembled the non-working unit, found a broken solder joint on the PC connector, carefully re-soldered it, and now I have two working sets. Price, who cares?
