Amazon Dash Wand
Echo owners have been able to order things with their voice for a while. The Amazon Dash Wand lets you order with just a scan. This Wifi-enabled gadget has a barcode reader on one end, allowing you to scan everyday household items and food products for reordering when you're getting low, has Alexa built-in, so you can still find recipes and do simple conversions with your voice, and is magnetic, so you can keep it handy. Oh, and you get a $20 credit in your Amazon account once you activate it, so it's practically free.
