On this subject at work we had been using Lenser LED headlamps for working underground and thought they were great. They were NZ$90.00 per set and we thought they were German made. We then found out they were "designed" in Germany. We found exactly the same(minus the Lenser name on the headband) unit for same on AliExpress for $3.00USD (say $6.00NZ) with free shipping to NZ. We ordered some in, they were identical. Just shows the mark ups that get put on gear sometimes. Probably went from China to warehouse, to Aussie distributor, to NZ distributor, to Engineering wholesaler, before we got our grubby mits on it. Everyone's putting a margin on but it was being sold as a "top of the line light system".
We have also received some absolute rubbish product and nearly been ripped off by fake companies.
I'm really interested in these "Daymakers" though and will await reports
