TL;DR: Cook perfectly every time, can't mess up. Easy to use, great app & controls, great support, heats up fast. Little cleanup (you throw bags away). Doesn't need much water for small cooks. Get it!I never thought a kitchen appliance will change my life. But Joule changed my life. Let's get the Pros and Cons out of the way:Pros:Magnetic BaseAmazing AppBluetooth & WifiAlexa supportedApp has great recipes and Visual Doneness temp guideGreat support & community1100 watts, temperature accuracy of 0.2 °F / 0.1 °C.Minimum water depth of 1.5 inchesAlarms set in the Joule app go off across all devices with the Joule app.Cons:Clip that comes with Joule is... just sad. (you can buy a Big Clip from chef steps but that's another 24 bucks)PlasticQC could be higherAlexa skill can't do timers (yet - more limitation of Alexa itself than Chefsteps).Android app video clips don't load smoothly. Sometimes just stationary image for a long time before loading - happens on both wifi and LTE.Joule:Let's talk about the Joule. Joule connects via Wi-Fi to the internet, so you can use alexa and messenger to set temperatures. But it also has bluetooth, and the Joule app seamlessly switches between the two! Joule also has a powerful heater, it heats a cambro 10L from room temperature to 175 in 20 minutes or so, during which you can prepare some fantastically smooth creme brûlée following the recipe and videos from the app. Basically anytime i'm cooking with joule, i'll start off preheating the water. Before i'm even done preparing the food to go in the bath, the water will be up to temperature.Joule has a magnetic base, a feature none of the other competitors have. You don't even need the clip if you're cooking in a steel container or a cambro + a sheet of metal under it. You just plop it down and it'll stay upright. (Though i'm worried overtime it'll lose magnetism since heat makes magnets lose magnetism...) It also doesn't need much water to work. When I make ramen eggs, I just use a small pot because the minimum water depth is only 1.5 inches - saves a lot of water.App:The app has lots of recipes, and generic temperature suggestions for items with no recipes. The recipes come with detailed instructions and videos on each step, and visual doneness. Visual doneness is basically clips of videos tied to a temperature that shoes you what it will look like when cooked at the temperature. (I've attached some pictures of the creme brûlée one). Back to the Wifi & Bluetooth switching. I was cooking a steak via Wifi when my comcast internet had an outage, and when I checked the app to monitor my cook, after 2 seconds on an "looking for joule" screen, it was automatically connected to Joule via bluetooth - with no intervention on my part, at all. (If your phone can't connect to Joule at all, you can also hold the top button for a few seconds and it'll stop the cook - sometimes I use it because I don't want to reach for my smartphone with wet hands.) The app could be a bit more optimized and faster, and there are some small bugs here and there, but the chef steps team seems to fix them quickly and i've had three updates since I bought the thing. Timers on the Joule App are great. It goes off on all devices that have the Joule app installed and logged onto, and across platforms. (requires wi-fi cook). If I set up a cook & timer on my Android phone via the app, the timer and up to temperature notification will also go off on my iPad and iPhone.Customer Service:When I first got joule, it made a weird sound when cooking and the water stream didn't come out straight from the spout (it shot to the right). I emailed chef steps with a video and they replied promptly saying their engineers listened to the video and that they agreed it didn't sound right, and will process an exchange - but since i purchased on amazon, they requested that i contact amazon - and it was painless. I had a replacement the next day that had burrs on the plastic body, but i cut it off with a razor blade and it's been flawless. (QC could be a bit higher, so i didn't need to contact CS or cut off excess burrs myself).Food:Oh my god. Cooking with water at precision temperatures is freakin amazing! You put food in a bag with salt and pepper, and when the timer goes off, it's perfectly cooked. you want rare? you get rare. you want medium rare? you get medium rare. Sear it on a hot pan for a few minutes each side and it's restaurant quality. Really can't mess up. Never have i cooked food that tasted so good and so perfect. From Steak to Creme brûlée (It's really delicious by the way... i make it every week now). Truly a life changing appliance.
