Joule ROCKS! It's lightweight, just over a pound (so easy to stick in your carry-on or suitcase when you travel), heats the water very quickly (1100 watts of power), temperature is accurate, the app RULES for easy operation on your phone or tablet (along with FB messenger and Alexa!), with hundreds of guides to get you from start to finish on whatever you're cooking, including Visual Doneness:tm: so you can see where you're going before you even start, taking the guesswork out of choosing the right temperature and time for cooking that perfect steak or roast, chicken, fish, custard, etc. And the ChefSteps customer service operation is the best in the business. They are quick to resolve any issues, answer questions and they don't stop until you're happy! So yeah, I love Joule....and I have five so I know of what I speak!!
