I have the Pro wired doorbell - best purchase I have made in ages!
I have saved countless trips to the local depot by having my packages delivered to my neighbour instead!
When my iPhone was delivered recently the delivery driver wouldn't leave it with a neighbour etc either. It was a Friday and I didn't want to have to wait the whole weekend to go collect it again, so I kept the driver chatting via the doorbell and quickly ran home and met him (luckily I work close to home!).
Im looking to buy the Ring Alarm Security kit as well since its now available in the UK - just waiting for the 14 pack kit though!
