Summary: I recently purchased a Canon 430 EX flash on Ebay. The flash I received was like new, but auctioned as a used unit. There were no scratches or scuffs on the unit. It was missing the box and the foot stand (a usual circumstance when buying on Ebay).
Summary: It works great with my Canon 50D. I recently got tired of using a cheap external flash, and since I am trying to take my picture taking to the next level I bought this flash. Great product Canon, as usual.
Summary: Whether you are a novice, or a professional, the 430EX will make life easier. Most novices won't use most of the options it has, like high speed flash sync, or the ability to control 2 slave units, but it is comforting to know you could.
Summary: I am only giving 4 Stars because I am comparing it to my 430 EXII. If I had not had one of those it would get a 5 star rating for sure. Great flash, fast, bright, easy to use. What else can you want.
Summary: Carrying around an external flash is always a hassle but the speedlite is streamlined compared to many other models and competitors. What I really like about it is that it has opened up new horizons of what I can do with my digital camera.
