@Joe Blowe, there is an Anova rep that follows the the SousVide forum on Reddit. Whenever anyone contacts that rep though a Reddit PM they seem to get a replacement, but it usually after they have posted their problem in the forum. It shouldn't be necessary to go that route, but it seems to work. My unit failed and I got a replacement on the first try with no questions asked by just emailing the support address. I have seen many reports similar to mine but also many like yours. Perhaps it depends on who gets your initial request.
As for the oven, so far I am not very interested. Sous vide has a lot of room for error in terms of timing so I rarely use the app (although I will have to use an app if my Joule ever gets shipped). Oven cook times are not as forgiving though so perhaps a temperature probe and a smart cooking algorithm will be a real advantage. I will definitely need to be sold on the usefulness of communication between the PC and the oven though. I wonder if that is mostly an attempt to gain a marketing advantage over their SV competition.
