Thanks, Kraken de Mabini and subsequent posters, for this informative thread, from which I've learned a lot. Before joining this forum, I was completely unaware that the Sea & Sea black strobes were produced in China and had issues (my blacks have been trouble free for several years, knock on cambium). In fact, I've been primarily a Sea & Sea strobe user for the past 15 years. Only once did I try the Inon Z-240 strobes, but quickly gifted them to a friend as I felt they were not very ergonomic. Certainly the stellar Ikelite strobe reputation and their unmatched customer service are enticing, but I decided against buying the strobe due to the proprietary battery, thinking if I'm out in a remote region of the world, I want to be able to purchase standard batteries if needed. I see Eli has devoted many hours to researching strobes and providing useful information on their functionality and repair tips. Thank you!
