Amazon.com has launched a piece of hardware that allows its Prime members to order a product by pushing a button. The 'Dash button', which is connected with the Amazon app through Wi-Fi, is brand specific and the company has tied up with household names such as Tide, Huggies and Gillette.

The Dash Button is simple to set up. Use the Amazon app on your smartphone to connect to your home Wi-Fi network and select the product you want to reorder with Dash Button. Once connected, a single press automatically places your order. Amazon sends an order alert to your phone, so it's easy to cancel if you change your mind. Unless you elect otherwise, Dash Button responds only to your first press until your order is delivered.

The button comes with an adhesive and a hook and can be hung or hooked anywhere in the home.

The offer, limited to three Dash buttons per customer, is only open to members who receive an email from the company with an invitation to receive a free Dash Button.
