It works as well as my Canon 600EX II- RT except that it has a battery level indicator AND it works as an optical S1 or S2 slave unit. It's not built as well as the Canon flash but these two items make it functionally superior. It's less than half the cost of the Canon unit too.

I haven't played around with this too much but I already love it. Perfect for most indoor situations this flash is going to help my photography a lot. I really like the fact that my camera can control it wirelessly.

Not bad for the price. However, some times it won't turn on and have to move the batteries.

Decent piece of kit. Works fine right out of the box. I was pleased with the purchase, though if I had more money I would have invested in the Canon version. Only issue is the manual is not very good, so you'll need to go to other sources to figure out how to use the equipment with your camera.

I had been meaning to try this flash for a while and finally did. I currently own two other Canon versions and so far here are the differences: The build quality on this feels good but swiveling the head feels less rebust. This flash actually has a startup time too (maybe .3 seconds?) which hasn't really affected performance either. Performance-wise, it seems to drain batteries faster. Once the batteries pass a certain threshold, the flash simply won't work. As far as the ETTL/exposure, it seems to consistently overexpose by .5 f stops. Again, nothing too major but worth knowing, IMO. I don't mind these setbacks though because I intended to use this as backup to my two Canon 600EX's and as a trigger. Definitely worth the price difference though!

I bought this flash as a spare in case I have to send one of my three Canon 600 EX Flashes to Canon for maintenance or repair. I also find it useful to have a fourth flash for the type of work I do. The Yongnuo is surprisingly similar to the Canon flash. The menus are a little different, but the flash functions fine and works well wit the Canon flashes. It even looks the same. There are differences and the build quality is less than that of the Canon, but for $ it's a pretty good deal. My Canon flashes are real workhorses and have lasted a long time. I am very curious to see how long the Yongnuo lasts...

The YN600EX-RTII unit is a cost-effective alternative to Canon's 600EX flash. Operating on the 2.4 GHz radio flash trigger system and E-TTL / E-TTL II metering, Yongnuo YN600EX-RTII yields a a powerful guide number of 197' at ISO 100 and 200mm as well as an impressive zoom range of 20-200mm. A wide-angle panel of 14mm coverage makes it an important tool for full-frame cameras. Bounce lighting is also supported with tilt from -7 to 90 deg and rotation left and right 180 deg.
In addition to wireless radio technology, Yongnuo YN600EX-RT supports standard optical pulse triggering for compatibility with both Nikon and Canon flash systems. In every flash the crucial factor is speed, which is why Yongnuo gave it a a recycle time of about 3 seconds and fast 1st and 2nd curtain synchronization settings. It also has a multi flash stroboscopic mode for multiple flashes during a single exposure. It runs on 4 AA batteries and comes with a case and mini-stand.
