@Dono i used to be on the anova fb group and found that there are owners who are on their 5th or 6th + replacement oven. all warranty replacements but that being said, i am on my second. but i managed to salvage my first oven so now i have two of these.
low reliability, but fast replacement warranty service (it's a poor business model but internals are cheap, they are not worth fixing). there is nothing reliable on the market with this many features and price point. a better oven would be a commercial combi oven that is overkill for the home.
