The BEST you can buy

Combustion Inc makes the literal best products. High quality, reliable, straight forward, and every detail was thought through carefully. I find the meters are always connected when they should be, the temperature readings are always accurate, and the app works flawlessly. I couldn’t be happier. I’ve used all kinds of products in this space and they all have their faults. I can’t find a single fault for Combustion Inc.

Terrible

Can’t get devices connected. Instructions aren’t correct and app is worthless.

Awesome product

Really love the thermometer, and Chris' YouTube science to go with it. Would be cool if the app had some extra features like saving graphs for historical comparison, an API to consume data for whatever you wanna do with it, maybe social features to share with other cooks what you're cooking with it.

Poor

The website is awful. My new thermometer arrived missing the charger. The email to “help” is not active. The instructions are poorly written. The app is frozen.

Waste of time and money

Probe is thin and easy to insert. Whole ecosystem just works. It’s next level. Recommended.
