Years ago, when I did a ton of travel editorial, I bought those Elinchrom monoblocks, trying to save on space and weight on the airlines. They were recommended by a strobe dealer in LA that I used at that time, (past tense). They broke down all the time. Not sure the deal with them, but very delicate design; were not designed for rough use or travel.
I have heard the same complaints about the Profoto monoblocks. It's as though every brand needs a "mistake", and the monoblocks were Profoto's mistake.
I have the 600B and the 7B, and honestly, in these crazy travel times, even they are too bulky and cumbersome. I'd love a steroid version of the Canon 550EX, or the Q Flash Quantum -- something not so plasticky feeling, with a real live stand adapter built in, that wouldn't snap off.
Not sure what happened with those monoblocks, but I rarely hear a good thing about them. It's a shame; perfect design for airlines.
