We have a Dot and 2 probes - one is designed to go into a food while it's in the oven... we hardly use that - wired ftl!
The other probe is for oil / sugar - I mostly use it when I'm boiling my raspberries after centrifuging them and adding sugar to get grenadine. Got some nice video of the probe at 217F while it boils away crazy yet stable.
This new gadget for our kitchen will not replace the dot, but I'm looking forward to using it in sous vide as well as the oven!
