I backed the Range thermometer on Kickstarter was totally excited about the entire concept. App worked OK but my thermometer stopped working after several uses. I contacted customer support (which was not easy I may add) and finally heard back from Risto apologizing for the delay and letting me know my Range was out of warranty and they were out of stock on my model but would be happy to give me a discount on an upgrade. Not sure why I would fork out another $50 when I already backed them on their Kickstarter campaign and only got a few cooks out of their defective thermometer. You would have thought they would have taken care of their initial backers and avoided the negative reviews - I will also be posting this on amazon. Great idea - poor execution.
