    Very good, works as expected, easy to setup and use. Go China!!! I left batteries in for over 6 months and they still work, no leakage.

    Great new lockdown ring added to positively attach it to the camera's hotshoe. This functions much like the locking ring on a flash head. The other BIG improvement is that Yongnuo relocated the power switch to the side of the unit so it is no longer covered by the flash head while in use. The switch now has Rx and Tx positions in addition to the off position. This takes a little getting used to and would be good to get familiar with before using it on an important shoot. Great product!

    Works great but I eventually upgrade to the YN-622C for the full TTL function. I still use these as a remote trigger

    No adapter needed. Works well with Altura flash. I'm planning to buy a second pair.

    Great improvement over the RF-603! Works on both Canon and Nikon cameras (though I am aware that the wakeup functionality only works on the bodies it was meant for). The switch on the side makes it easy to turn on/off as needed and the locking screw prevents the unit from falling off your camera! 5 Stars, A+++

    I needed to use my flash off camera and while this may not be in the class of the PocketWizards, it does a very good job. Using it as a trigger for my flash I can use it for long exposure shots. All in all very good product.

    These are so awesome and simple to use. I purchased 4 of them. Good quality. Good construction. It has the tightening ring so it grips the hot shoe well. I wish the power switch was a bit stiffer. They sometimes accidentally get turned on when I slide them into my case.

    Great quality, easy to use with my canon t5. You have to buy your own cable though. 2.5mm shutter cable. The 2.5mm has to be on both ends.

    Same as the review before, the concept of the item is actually awesome! oddly enough the transceiver "cancel" the shutter speed protection so you need to be careful not to go over your shutter speed.
