This Canon Speedlite 580EX Shoe Mount Flash is for parts/non-functional. The flash fires; however, when set to the off-mode, makes weird noises and then can't program the flash anymore. Still fine if set in slave/master. Will be mailed via USPS priority 2-3 day shipping. Will sell internationally through Ebay’s Global Shipping Program. Offer a 30-day money back guarantee if not satisfied with order. Feel free to ask any additional questions before purchase. Thank you!
