Agree with all of the above
I purchased two YS-D2 strobes three months ago for a big upcoming trip. I am very apprehensive about even taking them... way to go Sea And Sea. What was I thinking?
Now they release a new version that is actually supposed to work properly. I agree. There should be a recall on all Black Sea and Sea YS-D2 and replace them with the new version, no questions asked.
I am toying with the idea of taking my old Nikonos SB-105 instead. I KNOW they work.
