Anova Precision Cooker started out as a Kickstarter project where it raised a total of US$1,811,321 out of their initial goal of US$100,000 from 10,508 backers. It was shipped to backers in October 2014.
The Anova Precision Cooker is available in two versions, Bluetooth and Bluetooth + Wi-Fi.
I was using the Huawei MiFi E585 which I bought 4 years ago till the battery life decided to give up on me. The battery will go flat after about an hour of usage. On top of that I am spoilt with 4G because the 3G speed is way too slow in Singapore, due to bandwidth congestion.
