My range arrived quickly after ordering online and it works great. At first I had problems using it with an older iPad, but the Supermechanical customer support guys worked fast to make changes and provide an update. Ive since used it on an iPhone and a new iPad Air 2 and they all work great. Lots of great features to help you make the perfect roast. I love it!
