Me, I just use the Met Office app on my mobile, don't have to be where the weather station is located to eye ball it, gives an hourly or daily forecast and can access these for different locations.
Had some years back a cheapo weather station, never found it any real use and long since dumped when I discovered what I could access on my phone.
Can look at the weather vane on the adjacent building, if I need to know the wind direction at home, but a glance at the clouds gives a pretty good guide, and is free of local disturbances.
Use the £80 for, or towards two good meals out with the wife, very likely to be better received. Will also aid the UK economy not the Chinese's.
