I have a Godox. Great performance. 600 series, forget the exact number, think its a TT680., except it's badged as Neewer. It's THE SAME FLASH with a different name but same model number. Manuals are identical, just different name on the front. TTL is very good for the price, not perfect, but for £42.00 it was a saving of about £20.00 on the Godox branded one. In fact, Neewer do tons of rebaged speedlites, Godox, Yongnuo, Miele, and the new dual fit Nissin's (Canon and Nikon) as well. In fact, the Neewer was out before the Nissin, so it could be said the Nissin is a rebadged Neewer. So look at the many Godox guns on Amazon, then put Neewer and that Godox model number in the Amazon search box, and check the images and you'll see they're identical, apart from the name. Then enjoy the savings over the Godox name. Word of warning, not all Neewers are big name rebadged. There are two cheap ring flashes that fit on your lenses as well. The more expensive one of the two is also a Godox.
