Really not the same, results are very different. Can be positive a steak/joint will turn out exactly as you want with minimum effort, assuming you are willing to prepare 12 hours previously!
Hmm....I always thought a oven did this
I have the same and just noticed it's on Lightning Deal right now £79.99 - lowest ever according to the camels
We (well, my other half) wanted to try a sous vide machine and we bought this, rather stupidly named, Wancle (note to car enthusiasts - not related to the rotary engine of similar name) https://www.amazon.co.uk/Wancle-Precision-Immersion-Circulator-Black-Classic/dp/B01LYS24J3 Had it for 6 months - very good and reliable. EDIT: appears to be on offer at £80 for a couple of hours - quite happy for any reader to create a deal.
Cooked my steak last night with a sous vide...was lovely.
