I have this, and so far, it's lasted longer than 4x internal batteries (1x OEM, 3x aftermarket). Let me keep the LCD on for 5hrs+ and record about 2.5hrs last Sat at a drift event, where the weekend before, I could only use the 4 batteries for around 4hrs while turning off the LCD between shots. I actually bought 2 of those batteries, so I had them stuck to my tripod next to each other. If one died, it would take 2 sec to switch the plug to the new one instead of fumbling with an internal battery like the week before. Very handy.
