My only concern is the branded battery in this product - I'm afraid they will eventually change or discontinue the battery and then render the battery untraceable thereby rendering the flash unusable. This is both the biggest benefit of the V1 and what I worry about the most. It's advertised as recycling in about 1.5 seconds, and it really is. In my experience, for example, one battery will last all night on a wedding shoot, but like anything else, it's always good to have a backup, so getting a second battery isn't a bad idea for situations like this. I have read that some say that this flash does not work with Nikon's TTL flash and I can confirm that it definitely does not. Bounce flash, corner flash, direct flash, it doesn't matter, it worked great on my D500 and D7500. So if you need to shoot fast, the TTL flash is great. However, be sure to check before you head out so you can set the flash exposure compensation to your liking. I personally found it a bit brighter than I would like, so I used 0.3 less flash exposure compensation. But that's purely personal preference. I have a pair, with a 685N as a third light source and an X-Pro-N, and the simplicity of wireless flashing is so good these days that it really motivates me to try more and more. more ambitious things than the old days when direct flashes or PC sync cords were needed. For the cost of 1 Nikon flash I could get 3 great Godox flashes + wireless control and still have extra cash. Now I understand why people love these things, you get so much bang for your buck and the reputation is well deserved. So with all that being said, my only concern is whether a battery for it will be available for the next 10+ years. ? I do not know. That's literally my only gripe with this article, also, yes, make sure you research the Godox stuff before considering spending $700 on a specific branded flash, especially when there's no real benefit from specific branded flashes .
