Valeria was quick to respond and was able to get me a last-minute flash replacement in time for an event I was attending. The flash worked great and was well worth the time, money, and the rideshare to get it. My friend who returned the unit for me had some delays on the return date and Valeria was able to accommodate his schedule, which I appreciated tremendously. Thank you for all your help! I'm glad I remembered to check Sharegrid instead of giving up and trying to shoot everything in the dark that night.
