I've just received an S20, UK version with plug to suit UK power outlets, and that appears to work perfectly well plugging into either fixed power socket or into an extension lead. On the front there's a socket which looks like it's meant to be a UK standard one, but none of the plugs that I've tried can actually fit. The shutter is the wrong size or shape or something, and does not open when you try to plug in.
Anyone else come across this? It makes the device basically useless, the retailer has offered to exchange it or refund, but I thought I'd quickly ask whether this is a common and/or known problem.
