We've never seen this feature rich technology at this price!!!The outdoor unit supplements battery power by also using solar power with a internal rechargeable capacitor, meaning that you won't spend time changing batteries every few months. As an extra bonus, this weather station includes a 1 year UK warranty as standard.We normally deal direct with the main importer Weatherspares, which is why we pass you onto them to complete your purchase. However we are aware that sometimes Amazon run special deals, so for your convenience, we also check every day to see what is available.  The latest information is below, so just click on the relevant price:
