I gave a LOT of thought to going with the 1x5, and ended up (today, in fact) deciding that it just didn't work for me.
I do love the auto-off feature, but I think Big Blue miffed the implementation a little. The light cuts out for THREE SECONDS (and no, that's not configurable) with each shot. I don't know about you, but it's quite common for me to take more than one shot in three seconds, and beyond that, it's extremely rare for me to ever use shutter speeds over 1 second. I think the Fix/Fisheye Mini/Nano LED lights, with their 1 second cut-out, are about perfect. Three seconds is just too long, to my mind.
And the Big Blue is just that... BIG. Too big. Just too many little odd things with it gave me pause and kept me from pulling the trigger.
Instead, I went with the I-Torch VDO. Ordered mine today. It's more than the Big Blue, yes, but I feel like I can live with the feature set better, and it's smaller, lighter, and less intrusive than the Fix LED500 (which has the same price) or the Big Blue.
