This is hopefully my last and final update of the Cactus V4 by Gadget Infinity. I have given up on these cheapo products and have decided to go with the Cybersyncs. I sent back the 1st gen receiver and transmitter since the transmitter was faulty. After waiting about 2 weeks to get my replacement, I can finally test them again. I had also ordered an additional receiver. I tried to do more testing using the Cactus V4 and one of the recievers was not working. After wiggling around the hot shoe on it, it worked fine but once I removed it and put it back on, it didnt work again.
The one working receiver actually works fine and is pretty reliable but due to all these issues, I highly recommend against these units unless you dont mind the stress and trouble in dealing with getting them resolved with Gadget Infinity. I have exchanged numerous emails already about sending back the 1st generation transmitter and now I have exchanged more emails again about this faulty reciever. They said that there was no known issues with the receivers and gave me instructions on removing the extra clip on top of the hot shoe and said that might help with the issue. I tried that and still have no luck. The receiver is basically defective. Since Gadget Infinity is in Hong Kong, it is also troublesome exchanging emails since the time zones are switched and everytime I send an email, I have to wait until the next day to get a reply. Even if I send it during my nighttime which is their daytime, they are still not very responsive with emails.
I did manage to do two photoshoots with the Cactus V4, but only with one receiver, and they worked out okay but with all the trouble I had with these units, I refuse to use them anymore.
I just recieved my new pair of Cybersyncs so I can now return the Cactus V4 units for a refund. Unfortunately, the shipping policy of Gadget Infinity says that I have to pay for shipping even if the units are faulty. This is pretty lame considering that the unit was faulty when I received it. Hopefully others can learn from my mistakes and issues and if you still decide to purchase the V4s, dont say I didn’t warn you!
