As you would expect at this price point, you get a lot for your money - this is an excellent flash. Build quality is very good and it feels very solid. It has all features of a modern flash but does not cost a fortune.I used it with my Nikon D60 on a hot shoe mount with the TTL metering on. I have recently tested another flash at this price point and this K&F one works just as well. It is easy to use and the LCD screen is clear and readable. It has a back-light as well which is a very useful feature. Unit takes 4 x AA batteries but be sure you are using a good rechargeable or alkaline ones. Stay away from the cheap batteries as they just do not last very long in any flash and get depleted very quickly.Unit starts up and charges very quickly and is easily keeping up with my camera in burst mode. It communicates with the camera so flash itself is showing the current aperture off the lens and adjusts the zoom in auto mode. Even in full auto mode it produces good results and makes a difference to the quality of photos.What I like about this flash:- Guide number 56 - it is quite powerful and easily copes with shooting in large rooms- Rotation - it rotates vertically and horizontally making it easy to set up the way you want- Built in wide angle diffuser does a really good job- Back lit LCD- External power connector - you do not have to use batteries if shooting in a studioCONS:- cannot complain about anything really with this flashIn the box you get a carry pouch, mini stand, additional soft diffuser and instruction manual. Manual is quite comprehensive and explains all the various settings and an how to work them.I hope you found this review informative and helpful.
