The trigger is very reliable. 4 with the switches up to 16 channels are possible if they are needed for. Nice is that you can use the receiver as a receiver for the camera, and can remotely detonate as (optional, then you can not flash remote trigger) You can also submit pack a Nikon flash under the receiver, and remote-detonate with the Canon camera Nikon flash. So that should also work with all the flashes. Stupid is, however, that at the receiver at the bottom there is nothing to notice the flash foot. So if you set the receiver on one foot and it provides the flash, the receiver including lightning can back off slip from the foot when it is not level. In addition, a very strange format battery is used in the transmitter, which is likely to be in purchse quite expensive. There are no stand-by (as far as I have understood and observed it) so you have to watch that you both always off. For the money, there are also set with 2 receivers for 2 flashes.
Because the 4 criticisms a star a deduction, otherwise the parts are okay, so as 3-4 stars. Make absolutely sure that you are not the dealer from China order the rounds here, otherwise you may wait ~ 4 weeks and then pick up the equipment at customs and pay extra fees ... or refuse to accept, again wait for 3 weeks and then and prefer to order directly from Amazon ;-)
