The first few shots work fine, but between shot 3 and 6 the screen goes dead and will not restart for 3 or 4 minutes. Sometimes it goes back to a solid red light and sometimes it starts a flashing red and will not fire, sometimes just complete blank screen.
The unit you sent definitely has a fault that causes it to die after a few flashes and my SB-900 behaves fine with the same batteries. See my other Nikon ads.

Wireless control allows you to employ the SB-900 as a remote light source for brighter, more professional shots. As a successor to the SB-800, the Nikon SB-900 Speedlight is larger than previous flashes, such as the SB-700. It was designed with practical functionality in mind, and photographers will notice a difference in the quality of their photos, especially when pairing this shoe mount flash with compatible Nikon digital SLR (DSLR) cameras, like the D700. 180-degree left or right head swivel allow for more versatility, and a wider auto power zoom range of 12 to 200 millimeters in the DX format delivers professional-looking photographs regardless of the situation. The Nikon SB-900 Speedlight is simple to control and comes with streamlined menus for ease of use.
A rotary dial lets you set functions more quickly, and a master and remote control switch makes wireless operation a snap. To power the flash on, simply switch on the rotary dial.
When new features are available, simply download the updated firmware onto a memory card and upload it once the flash has been mounted onto a Nikon DSLR camera. This ensures that youll always have the latest advances available for your Speedlight, keeping it up to date with technological advancements.
The included manual has all of the information you need to use the controls and keep your SB-900 updated. Technical specifications of the Nikon SB-900 Speedlight include a guide number of 111.5 feet at ISO 100 and 157.5 feet at ISO 200; lens coverage of up to 200mm; and tilt range from -7 degrees up to 90 degrees, with the ability to rotate up to 180 degrees left and right. The flash comes with three light distribution pattern modes that help optimize light quality, and overheat protection for the flash tube helps protect the Speedlight during sustained high-speed bursts. The Flash Value (FV) lock feature lets you lock in flash output on your chosen subject, regardless of aperture or zoom position.
The minimum recycling time for batteries range from 2.3 seconds with Ni-MH batteries to 4.5 seconds with lithium batteries, though the flash can also accept the Nikon SD-9 battery pack. Several accessories are available for the Nikon SB-900 Speedlight, including a Speedlight stand and a SJ-900 color filter set. Even without accessories, the Nikon SB-900 Speedlight is a versatile i-TTL flash that provides the lighting you need to take quality photos. Its commander mode allows it to work within a system, though it works just as well as a standalone wireless flash.
