I wonder whether these were imported here, or this one came with an immigrant to this country. I have not seen this model before on these shores.
Hmm, the non-Oz plug(s)/sockets seem a giveaway- import. Not a plug aficionado so can't speculate on possible source. Maybe not even 240V. Note the comment in the ad:
Please study the photos as they are part of the description
Even if 220/240V, and I suspect so judging by the cable thickness, if it is designed for 60Hz (we run 50Hz in Oz) you'll lose some performance.
EDIT: All right, I admit there's a
slight chance it was exported from Oz, the plugs changed and since reimported. But unlikely, hey?
