I bought a Nikon D40 to take pictures of our new son, and wasn't happy with the way flash pictures looked: too harsh. I bought this unit for its bounch flash capability and have been very happy with it. It's small, light, and uses two AA batteries. It communicates very well with the Nikon: for example, the camera knows when the flash is aimed up, it does can do very nice redeye reduction, and the user can control the power of the flash. The recycle time is just fine. I wouldn't recommend it for shooting big groups of people in a very large room with high ceilings, but it's perfect for shooting inside a house with standard-height ceilings.
