Of all the useless devices the SMS kettle really does take the biscuit.
For a start you have to fill the thing with water, and it’s only a kettle not a teasmade, so after you have sent the text message “switch on” to the kettle you then have to check if it has boiled, and then pour out the water onto the beverage of your choice.
Couple that with the fact that I don’t have mobile coverage at home the SMS kettle appears to be the biggest waste of time this week.
