Affectionately referred to as an "ebay trigger" or by various word plays on leading trigger brand "pocket wizard" alluding to their shall we say extremely economical nature, these babies are cheap and versatile, providing a multitude of ways to trigger flashes, most tempting of which for a cheapskate like me is hotshoe to hotshoe as neither my flash or DSLR offer anything so decadent as PC sockets. A boggling host of adapters for cables that apparently do but probably shouldn't trigger a flash are included in the box, so you shouldn't have any trouble if you don't want to go down the hotshoe route - or, intriguingly, if you want to trigger multiple flashes from one receiver.
A few words of warning should be mentioned, I feel. Firstly, run the receivers off alkaline AAA batteries only, they got exceedingly grumpy with NiMH eneloop rechargeables, as in the range dropped to about six inches - iShoot, destroying the environment two AAAs at a time. Secondly, there's no tightening screw on the foot under the receiver, so if your flash/umbrella stand setup requires a foot/shoe connection to hold your flash in place rather than a screw, then you're going to be weaving elaborate webs with electrical tape to make sure your flash and receiver doesn't go for a short-but-terminal tumble. There's a standard screw fitting, though, so this may not be an issue for most.
All in all, these represent outstanding value for money and consequently somewhat less-than-stellar industrial design and build quality, but with two receivers and a transmitter going for under thirty quid with batteries you can't really go wrong. Pair it up with a YongNuo speedlight, a cheap stand and umbrella, and you can have a complete kit for about a third to a quarter of the price of a "decent" speedlight on its own.

Great affordable set of triggers. Have used them with a Canon 40D on both studio flash units and 580exii. The direct plug socket into studio flash seems a better secure fit than others I have used with cables. Used these on a 6 hour shoot the other day and not a single misfire.
Very happy with these and may well be ordering some more...

Excellent addition to my kit. I was surpried at how small the units are but they seem sturdy enough. My only quibble would be the placing of the leds on the receiver units - they are hidden from view when I use the larger of my flashguns.

Great items that do exactly what it says on the tin.
This is a great piece of kit. It works perfectly on my Canons DSLR's and I can't see what extra benefit you would gain from buying similar products at 4 or 5 times the price. Read more

Cheap AND effective
I actually bought both the A and S kits, each with two receivers because I have a mix of kit, speedlights and other flash equipment. Read more
