Thanks all for the replies - I'm hoping to have a good tinker around with all of the weather functions - notably my wind speed readings are currently completely inaccurate, so that will be a welcomed change!
Anyone any advice for the best mounting position, I was thinking of putting it on a high fence in the open at the back of the garden, the current one is mounted on a line post!
If you can afford the extra it may be worth changing to the Pro2. Good luck, and I mean that.
Unfortunately with the wireless system and logger in the region of £600 - it's too far out of my price range
However, I was recommended the Vue by a friend of mine who has a weather station nearby, he's had it nearly 6 months without any trouble - so I think I shall see how it goes, if I had the extra budget I would have purchased the Pro 2.
