Hello everyone. I spoke with David about the EL issue and he says this is a problem on 2-3 pairs of each size. He claims it is not an issue with the electronics materials, but rather the way they were assembled by a certain factory worker(s). He says all correctly assembled pairs should be very durable. He has worn a pair for 15 days, put them through stomping stress tests, and has assured me that the ones that don't fail immediately will be fine.

Everyone who got a faulty pair is entitled to a new pair free of charge. Just contact him on Skype, verify that you are an owner of a faulty pair of Mags, and he will make the arrangements to ship a new pair.
I also spoke with him about getting the technical diagrams and/or details on the electronics in these things so those of you intent on modifying them to change the brightness of the EL and LEDs will have an easier time. So stay tuned for that.
