Review on Foto&Tech Wireless IR Remote Control for Sony A7R IV III II, A7III A9 A7 II A7 A7R A7S A6600 A6500 A6400 A6300 A6000 A65 A77 A99 A900 A700 A580 NEX-7 NEX-6 NEX5T - Video Photo Modes (2 Pieces) by Bobby Posner

ordered 2 packs. One of the remotes only worked about 6 shots. The remote control didn't work at all. The battery in this remote control has very strong signs of corrosion and is certainly not new. I removed that battery and put in another battery to see if it works. There is no such happiness. I don't usually write reviews because I don't have time. But this product had so many good reviews that I was very happy with the purchase. However, in the end I think you get what you pay for. Maybe I'm unlucky enough to get 2 bad versions, but it was still disappointing. Now there are 2 non-working consoles. If I took them for field work and relied solely on them, I would be in a bad position.
