Amazon's Dash Buttons, interesting little devices that allows you to easily order household items by simply pressing a button, are now available to Amazon Prime members for just $4.99 each.

When Amazon first announced the Dash Buttons on March 31 this year, many suspected the strange product was an April Fools' Day gag. However that's clearly not the case, with Dash Buttons expected to reach the doorsteps of Prime Members who buy them by July 31st.

There are currently 18 Dash Buttons available, most of which cover cleaning product brands such as Tide, Glad, Cottonelle and Bounty, although you can get Buttons that quickly send you more Kraft Macaroni and Cheese, Gatorade, or Gillette razors.

The buttons are tied to a specific brand rather than a specific product, meaning you can set up a button to order whatever product from the brand in whatever quantity you desire. For example, you could set up the Tide button to ship you a 95 oz box of laundry detergent, or a pack of Tide Pods, depending on what you use on a regular basis.

Dash Buttons are set up and managed through the Amazon app on your smartphone. To prevent a user from accidentally ordering multiples of the same product in succession, only the first press will order the item, resetting when the order has been delivered. However there's no stopping a child pressing the button unnecessarily if you're already stocked up, as that order will be placed immediately.

The Dash Buttons are currently a "limited release" for Prime members, so if you really want to get one, you might have to do so quickly before they sell out.
