Bought from new, boxed and in excellent condition. I've owned the Canon version and this Newer version and this is better made than the Canon original ringflash. I've used this flash on Canon EF so I know it works with all the Canon EF compatibility for the EF range. As for other Canon model ranges, I don't know, apart from manual compatibility, if this works with any other compatibility. The used condition is "like new", in full working order and comes in the original box. Happy buying :-)
