That sucks. I'm interested to see how they respond, seeing as your issue is actually something failing, I imagine it will be rather quick. I never did hear back when I was trying to troubleshoot the lame board, but it may have been low to no priority as it was in spec.
Reading through Pangolin's support info, you may get away with only having to ship back the hashboard, but they might not have updated the information lately. Definitely better than sending the whole unit in for repair.
FYI, my total customs+duties on the unit (with the USD51 discount code) came up to CAD68. So all in all, very positive experience so far. I'll post an update once the unit has run for a few hours on wintery Canadian sunshine electricity.
Nice one of those low tax provinces, I get hit pretty hard on everything I bring in. Enjoy, so far my 2 have been pumping the heat nicely to fight the ridiculous cold.
