"I am a co-owner of a coffee shop and this was moderately intriguing. I would tend to agree with John Davies not to put ice and milk into perfectly good coffee, but I don't get to choose what people order and an iced mocha requires a considerable amount of stirring if you want the chocolate sauce to be mixed into the drink properly. The amount of energy that this devices consumes doesn't make a bit of difference after you account for the 5 refrigerators we have (we sell beer and wine also) and the coffee brewers and espresso machine that are always maintaining water at 200 degrees F in the boiler. I don't think I would put this in my shop for the barista to use because it would slow the workflow down. Anytime you have to put a cup down and then pick it back up is a loss in time. A barista can swirl, stir, or shake a drink faster than adding an additional step to the workflow. I could possibly see it used on the customer side. It may be a novelty for a customer to use as they pour their 8 packets of sugar free sweetener into their handcrafted beverage."
