I have an Inkbird & really like it. Significantly less expensive than Annova, offers all of the same features from what I can tell, & it’s never given me any issues.

The app is of course a bit clunky & ultimately unnecessary, but it does actually function as advertised.

I don’t actually own any of their products but the bbq community generally speaks very highly of it. I figure whenever my current SV stick dies (not an ANOVA, it’s a knockoff from Aldi lol), I need a backup so I’ve kept an eye on the market…
