Review on Neewer VISION5 400Ws TTL Flash Strobe for Sony Cameras – HSS Monolight with Wireless Trigger & Long-lasting Battery: 500 Shots, Fast Recycle Time by Brad Arthur

Unfortunately I had to return the product because it doesn't work properly with my Sony after using it twice. I want to clarify that ALL THE DEVICES I USE IS NEW when I tried this flash. It happened to me that in some cases the flash worked and in others it didn't. Regardless of the mode (Manual, Multi, TTL or HSS) or control, the chosen speed, wrongness or controller (I could not eliminate my doubts) did not respond. The failure was accidental. I knew 3 photos in a row and it was perfect, then I took 3 more and failed on 2. I've even had occasions where a photo taken at 1/80 was half faded. I attach examples of photos with an error. I must clarify that the build quality of the flash is very good. The accessories and parts included in the kit are of very good quality. If it hadn't failed I would have kept it and worked with it.
