Review on TheLovelyBird 4PCS Cell Battery Holder by Jaxon Prince

I love these things! I'm a wedding photographer and I keep running out of batteries in my flashes (everyone uses 4 AA batteries). I only take a couple of these with batteries pre-charged so I know which batteries are good and ready to plug in strobes. Then when the batteries run out I throw them in my bag and take them out to charge when I get home. Once charged, they return to their cases for the next performance. The falls are strong and remain closed, so I'm lucky!
