When you first open the pouch the flash comes in (which is good quality) you will be pleasantly surprised! The flash, although incredibly plasticy, feels relatively sturdy! On inserting a set of batteries and pressing test, you will get a nice, high powered flash of light to greet you! I find the rear interface a little clunky at times but with a bit of work you can easily get great results! There is a small diffusion window that slides out above the actual light lens itself and this works adequately although I'm not sure what level of diffusion it is equivalent to. The flash head movement is firm and strong. On the horizontal axis, the head moves smoothly without being loose and on the vertical axis, it offers a reassuring level of resistance that doesn't hamper you as a user. My pet peeve which is applicable to all Sony hotshoe mount products is the utterly ridiculous Sony hotshoe mount but there is no way round this since Sony made their own standard. Overall I rate this flash highly, and if bounced off a surface, produces beautiful quality light.
