Since this set is a fraction of the price of the ubiquitous Pocket Wizard, I thought I'd be banging my head against the wall using them. Nope! They are great.

WARNING** DO NOT BUY THESE ** 1 by .. T. Grimes (NY,NY)
I bought these flash triggers trying to save some money. I am not a Pro and I thought they would be fine. Well, first I was told that they shipped a few days after my order and given a UPS tracking#. I kept looking in UPS, but the number didn't show up. Turns out they were actually shipped 7 DAYS AFTER I received the tracking number. So I waited and finally received triggers. The Transmitter worked but BOTH receivers did not. I am very familiar with different triggers and electronics so I know it was not an error in setup. I tried them on every channel as well and changed the batteries to brand new ones. No Dice. I got an RMA # and had to return them, out of my pocket ($10). They received my return almost 2 weeks ago and I have not heard from them since, They have not refunded my money or responded to my emails yet either. Better off spending a little more on the Radio Poppers. Thats what I did and they work great! DO NOT BUY THESE!!!!
