The KF-570ii is quite a good piece of kit with a decent build quality and bright output. This flash has a lot of power, but it tends to be focused on the center of the image. This means that the flash would be best used in a studio setting as a manual remote flash with a diffuser such as a softbox. You must understand what you are purchasing before you buy: this is a fully manual flash, meaning it will not automatically determine exposure. If you can find a use for a fully manual flash this is a good product to consider.
