I've had an anova for several years and love it, but it's not the end all, yet another tool that when used correctly can deliver delicate items to perfection.
If you're cooking 1 or 2 steaks at a time, and they're not several inches thick, it's a waste of time. If you have a big thick steak(filet), even with the reverse sear method, you can't accomplish edge to edge pink with no gray any other way. I stopped adding anything other than SP to my steaks in the bag. Finish a few degrees below desired IT. Pat them dry and let them rest for 10 minutes before finishing.
Seafood is very good from the Anova.
Great for meal prep as you can make a bunch of individual packed stuff. Great for parties when everyone isn't eating at the same time.
Really good for perfect vegetables because they tend to be over cooked.
