Yep i bought an Anova, you can often get them half price for Mothers Day / Fathers day deals, i think its a great tool,
I have cooked pork joints, Lamb Shank, Steaks, boiled eggs, as previously said browning the meat is required, steaks i cook then sear in a really hot pan, then rest before serving.
I modified a Coleman coolbox by drilling a hole in the lid thats a tight fit for the anova, so it keeps in the heat and stops evaporation
