The low-profile transmitter hugs low on your camera's hot shoe, thereby avoiding mishaps like broken shoes and other pitfalls of oversized units. A test button facilitates the taking of flash readings and system checking on-set. The radio signal is unimpeded by walls, windows etc. and operates within distances of 200 feet at a high maximum sync speed of 1/180 sec. A 10-channel selector on its underside keys into the corresponding dial on the receiver to trigger the connected flash or camera without interference from other devices. The transmitter is powered by a long-life, inexpensive A23 alkaline battery. Trigger voltage is under 5V, making it safe to sync with virtually all brands.
The design of the PowerSync10 DC (battery powered) receiver is driven by convenience and compatibility at every stage. Measuring only 2 x 4" inches and finished in matte black with a grippy, nubbed surface, it features 3.5mm mini as well as a PC jack. As further evidence of forward thinking, topside hot shoe and underside 1/4"-20 female threaded mounts are incorporated.Photographers who like to travel light could conceivably assemble a wireless mini studio comprised of several shoe-mount flashes equipped with PowerSync10 receivers, that fits in a small shoulder bag. Also included, are a 3' coiled mini-mini cord with phono plug adapter to jack into flash heads or power packs. Two adhesive-backed accessory shoes and a 1/4"-20 thumbwheel enable mounting to a flash head. A reusable cable tie is also provided. A wide selection of adapter cords accommodate most brands of flash equipment. An optional AC adapter is offered for studio use.

I got these as a cheap alternative to Pocket Wizards or Bowens Pulsars for triggering my flashguns.
I use them on my Vivitar 285HV's and my Nikon SB600's. They work great on both model flashes, and have proven to be very reliable. Not a misfire yet, in about a month of use.
The on/off switch feels very nice; a weird thing to comment on, I know, but it's true.
My only concern is, with my SB600's, the triggers don't lock in very well. No problem at all with my Vivitar flashes, which latch on rock-solid! I believe this more has to do with Nikon's design, rather than a failing of Impact. In either case, it's something SB600 owners should be aware of. I get around it by using twist-ties, just as insurance from accidents.
All in all, great product for the price. Very reliable. Easy to use. A good buy.

Just got these little guys today and they work fantastic! So far I've not had a chance to do a full shoot with them but I've been playing around most of the day. They work great with my Nikon SB600 and my Speedotron power supply, no adapters needed or anything.
The only concern I see currently is the plastic feels really fragile and cheap, but I think if your careful and not too rough with them they should last a good while. But for the price difference between these and pocketwizards I think I can live with that untill I can afford a set of pocketwizards.
Outside of that I have no complaints as of yet.So if your looking for a set of radio transmitters/recivers and pocketwizards are out of your budget then I would suggest giving these a try.
