It's been an excellent addition, that's for sure, and I use it a lot. Follow the time and temp instructions and stuff comes out about perfect. You'd almost have to intentionally do something wrong to mess up.
I am going to look for a better container though, some sort of insulated type. The big metal pot I'm using must allow significant heat loss, and I'm sure I must be wasting a lot of electricity. The Anova has zero issues with keeping the water at the exact temperature, but it must heat constantly.
I was doing another long cook at 131 degrees for three days. On the evening of the second day I wanted to do some scallops. I went ahead and dropped the temp setting to 122, as the recommendation for them was at 122 for just 15 minutes. Then I would just zip it back up when they finished. It was quite an eye opener.
I spun the wheel down and set it at 122. Before I even got the temp set the water temp was dropping, and within what seemed like just a minute or less it was at 122. Made me realize how much heat I'm losing off the pot. After taking out the scallops and resetting to 131, it took quite a while to get back up - seemed like 10 or 15 minutes.
I'm going to do some searching to see what I can find for a insulated type vessel. I could probably just use a cooler, but I think it would look a little tacky sitting there. I have it set up and running much of the time.
