I love OpTech products. but I think they missed the mark. Batteries for my a6500 fit in there perfectly. However, the way it "attaches" to the strap just doesn't work. It also gives the impression of being built backwards as the valve closes inwards rather than outwards. This can be extra protection to keep the batteries from flying out. A bit impractical and seems like I installed it wrong all along. OpTech can do much better than that.
