    Love the YN-E3-RT for what it is, but with a few caveats.
  

*by S***E on Reviewed in the United States on December 3, 2016*

I've had mine since May '15 so I've put mine through the ringer a bit. I bought mine mainly because of the price and the AF assist beam compared to the Canon ST-E3. Was seriously considering the Canon version when I dumped my 580EXII for 600EX-RT but I don't regret not buying the Canon version a bit. It works perfectly with my 1Dx/5DIIIs controlling 3x 600EX-RT. The AF beam proved to be clutch, even with its somewhat off-center, funky-looking pattern.Now, for the negatives: The AF assist beam doesn't seem to work with I mount the unit to my 1Dx MkII. Everything else works but that's just unfortunate. Really hope Yongnuo can update the firmware to address this bug. Also found out the YN-E3-RT will trick the 1Dx mkII into limiting the shutter to its flash sync at 1/250 even if the transmitter is turned off. Which means you'll have to remove the unit (instead of just turning it off) from the camera if you want to shoot at a higher shutter. It's no big deal if you're just shooting around, but it's an annoying extra step while shooting a event. Was going to order a second one but I am going to wait until it'll work properly with the 1Dx Mark II.

    ... had this for about a month now and I love it compared to what I use to use
  

*by G***N on Reviewed in the United States on January 27, 2015*

Ive had this for about a month now and I love it compared to what I use to use, which was just some cheap wireless triggers off of ebay.  I have been using this to control my Canon 600ex rt off camera outside on location in 32F give or take weather.  The range is great, I have not exceeded the range of this.  Power consumption, I got about 400 shots before the two rechargeable AA's died, so not bad but not great.  The display has gone bezerk a few times, but keeping in mind I am using this in freezing conditions, hopefully that wont happen during the summer.  And when it gets really cold the screen is slow to update as you change the power settings.  This seems to be worse in manual mode than auto.My only problem is that the power adjustor is hidden in the manual mode, you have to press a few buttons before you can change the power, it should be on the home display.  ETTL is a bit easier to adjust the power, you only have to press one button instead of a few.Other than that, this is a great device, well worth the $100.

    Requires firmware to work with 430ex iii-rt
  

*by T***M on Reviewed in the United States on April 18, 2016*

Just adding one more confirmation, without firmware update it did not work with my 430ex III-RT at all, but after firmware update it's working perfectly with my 430ex III-RT (III has wireless, unlike II)I had to download two programs from the yongnuo website (I downloaded them onto a virtual machine so no virus/malware could be on my main one, it's often a bad idea to install obscure chinese software on your main computer), plugged device into usb and updated the firmware on it. 5 seconds later it was perfectly controlling both my 430ex III-RT wirelessly just like the official device, and for something like a quarter of the price.A few minutes of extra work is certainly worth saving three hundred bucks in my own opinion.Though the real drawback is I've heard if the device does malfunction sometime in the future, the cost of shipping to china, questionable repairs and wait time may make it easier to simply buy a new one.Of course, if the alternative costs as much as 4-6 yongnuo transmitters, it's hard to be mad about eventually having to buy a single cheap replacement or two.
