Cactus Triggers v4 from Gadget Infinity. One word “Cheap“. Cheap look. Cheap buy, Cheap Build quality. Yep they work and have allowed me to start down the strobist path, but I am already looking at replacing them with possibly CyberSyncs. Can’t guarantee that they will fire all the time, in the short time that I have had them I have experienced several miss-fires. I bought 1 transmitter and 3 receivers.

Aptly “Cactus” is an Australian colloquialism for being stuffed.
