5 Stars What a difference!
Wow, totally dig this flash! After using the built in flash since owning my D40 (& not being happy with the results alot of times!) for 2 yrs, this is so refreshing & inspiring! I saw reviews on amazon with photos of what this flash does & it’s totally delivered 
Beautiful results from bouncing the flash off the ceiling. This was one big easy step in furthering my photog hobby skills!
4 Stars Fantastic lighting upgrade
I have have been using this unit for 2 weeks and am impressed with the improvement offered with indirect light bouncing off nearby surfaces vs the on-board unit. The SB-400′s capability to aim the flash in multiple angles is not thoroughly detailed in store or official documentation when it is easily its greatest feature. I sometimes wish I whent with a flash with a bit more horsepower and twist aim, but I figured learning the art was more important than the gadget. Overall a simple no frills great improvement from my D5000′s on board flash.
5 Stars For users with a Nikon with ittl only “D40″
This add-on flash is compact and works flawlessly on Nikon camera with iTTl systems. Using the built-in camera flash will consume your cameras’ battery life a lot faster this possible causing you to lose that perfect moment. There are huge benefits of bounce over compared to the direct flash on the Nikon model and body you own, maybe overwhelming. This unit gets great reviews for its size and its multi angel bounce, this unit will bounce off high ceilings and distant walls but it’s great for many occasions and engagements.
Overall by using this unit instead of the built-in flash of one’s camera, you will get more shots from the camera since its power source is two independent AA batteries and not the camera. It’s compact it’s great for its size ability and price.
3 Stars Not as good as the SB-600
I got this to go with my Nikon D40. It is an improvement from the built-in flash for sure, but not as good and versatile as the Nikon SB-600 Speedlight Flash for Nikon Digital SLR Cameras. I ended up returning this one and buying the SB-600 instead.
Pros for the SB-400 are size and price – best for portability. It is definitely an improvement over the built-in flash for light quality and ceiling bounce.
Biggest weakness is that I can’t use it for portrait photography bouncing off the ceiling. Please see review of Stroboframe Press-T Flash Rotating Bracket for details.
5 Stars Travel Light
While not as versatile as the more expensive and featured Nikon flashes, it does the job while remaining small enough to throw in the camera bag for small events, parties, day trips, etc.
