Amazon launches Dash gadget to let you restock kitchen with a whisper

Dash, available in the US since 2014, will let shoppers reorder groceries by scanning barcode or saying name into microphone

Amazon is stepping up its assault on the UK grocery market with the launch of a gadget that helps restock the kitchen cupboards with the scan of a barcode - or just a whisper.

Shoppers who use the online retailer's new fresh food and groceries service, Amazon Fresh, are being offered the Dash gadget, which has been available in the US since 2014, free with their second order. Amazon Fresh is currently only available in some areas of London.
