This was very easy to set up, connecting directly to my router. The display, that refreshes every 6 hours, on connecting updated within 10 minutes. The unit can be configured, from the PC, using the software provided on CD and I was easily able to set the unit's location to the (UK) town in which I live.
The unit is a bit smaller than I expected and the coloured display is perhaps difficult to read in bright daylight, however the details are easy to read in the right lighting conditions. Note that it does not show actual temperature etc. - only the 'forecast'.
Another good point is that once configured, the PC does not have be running for the weather forecaster to update.
