Read a lot on the net. Learned times/temps from more seasoned eGullet members
I’ll often google something I haven’t tried, review all the different methods and look for commonality and then learn from experience
There are some good websites and apps
Chef steps is a good website and app
Sous vide dash is an excellent app and highly recommended
I use Cambro polycarbonate or polypropylene containers with lids. A cut out in the lid for the device and sheet foam to cover and gaps around the device. You want to retain heat and reduce evaporation. Always start with water close to your target temp if you can. Hot tap works well. I use a UPS back up power supply just in case of a brief power interruption to be on the save side. Never want to come home and see the unit on stand by. Eek!!!
Also protect your contertop from prolonged heat. I use a wood cutting board under my containers.
If I got the new wifi anova I would use the wifi to check on the device and make changes in temp while away. The Bluetooth lets me do that from my couch. Worthless
