What is a backer ID?

The number you quoted, that’s what you see on Indiegogo when you look at your Contribution ID?

Then that number for ordering in October could be right indeed, as like @MaximeM correctly stated:

So there were many orders possibly cancelled.

In the end, like I’ve stated elsewhere, all you need to do is keep following the updates in General info about shipment and manufacturing - #352 by Philips_Support_N
and patiently keep waiting. Most challenges have been overcome so far, the units are being made and shipped, so yours will get there soon! :wink:
