I was going to buy a Canon flash until I saw the Godox. So far it has performed well and does feel well constructed. The ttl works perfectly and I like all the features the flash offers for the price. I have heard a lot of complaints about the life of a Yongnuo so I went with the Godox.

Great product but after a month or so it wouldn't turn on unless i opened and closed the battery door with the switch turned on. I should've sent it back then but didn't get to it now it wont turn on. Maybe it's just some loose soldering but I didn't drop it and it stayed in my camera bag.

Much cheaper than getting the OEM Canon Speedlite 600EX II RT. You can probably buy 4-5 of these for the price of one Canon Speedlite. The build quality is very good and in my opinion seems much better than the more popular Yongnuo brand flashes.

I occasionally use speedlites, which have been a couple of Canon 580ex. Lately I have been doing some strobist type setups with speedlites for quick environmental portraits, sometimes using cc gels to balance colour.

This flash is amazing. I've used Canon speed lights for years, I purchased 2 865's to use one to trigger the other and they worked perfectly. I'll be purchasing more to replace all of my worn out equipment. The price is amazing, and so far not 1 complaint from their performance.

The only reason I didnt give this 5 stars is I havent used it much yet and I havent been able to get the optical wireless firing to work. I did get to use it once for a portrait shoot shortly after I got it and it worked great.

For those who want to spend a little less, it does the job just fine!Ive found just one negative aspect: Slow low light auto focus assist for the camera.Besides this, very powerful and durable

Not a bad flash for the money but the autofocus assist light failed after a couple of months. Godox was willing to fix or replace it, but I never had the opportunity to send it in. I just want a flash with a really good autofocus assist light.

Used it the first time today shooting a Christmas Fellowship Program. Its performance was virtually the same as the Canon flash. Powerful flash. Will order a second one for backup.
