The useless dash buttons are dead! This can scan barcodes and hear what you want for your shopping list.
I presume once you've scanned your product packing before sticking it in the bin you can view the list of shopping needs and decide if you want to delete it (buy it locally when out in Aldi/Asda/Lidl/Morrisons/Sainsburys/Tesco etc. or let Amazon Fresh deliver if the price suits.
Getting your money back for your inital outlay (just like the old dash buttons) makes it an easy decision.
Exclsuive for Amazon Prime & Fresh customers.
