Review on Improved Neewer 16 Channel Wireless Remote FM Flash Speedlite Radio Trigger with 2.5mm PC Receiver for Flash Units Featuring Universal Hot Shoe Compatibility by Wanda Kolb

Amazing. Works perfectly on my a6000 and Meike MK-930 II flash. The flash leg was a bit incompatible, but with a little mod to mount the flash backwards I was able to get it working in no time (5 minutes). See my flash review for details. See attached image for motion capture - so much glare!. Also works without mods with my old Vivitar Thrystor Flash. I have this flash for an old Minolta SRT 101 and I believe many other flashes will work as well. I think I only had problems with the Meike MK-930 II because mine is designed for the Sony MI hot shoe which places the electrical contact deep in the foot. Many people have complained that they fail after a while. I suspect this is because the transmitter's internal battery died at some point. There's no obvious way to replace this battery, but I think I'll know when mine's dead - and then I'll grab a screwdriver and see where it takes me. In any case, for €15 you can't go wrong here.
