I have a handful of FWXs. I had to work on each to get it to work properly. Just like LuminTop, I couldn’t be bothered to update the software (firmware), but I had to correct every physical problem mentioned in this long thread.
I coworker liked my grey FW3A enough to have work get one for use as an illumination tool. I must say, the fit and finish of that one is superior to mine and is even serialized. And, after a week, there were no issues from right out of the box. This includes Muggle Mode. Which helps me believe the SW (FW) has finally been updateded.
Hope this is a continuing trend with LT.
