You pretty much answered it in any case - if you're cooking something the size of a leg of lamb, how good is the little wand at bringing the water back up to temperature once you put the leg in.
It's a bit moot, to be honest, as at some point, it's either deal with whatever performance the sous vide wand has, or spend £££ on a commercial machine.
I do like the coolerbox idea though, and may well copy it.
I've also found something on github where someone has written something to access the Anov API, meaning that it can all be integrated into home assistant.
