Any forum members out there own a sous vide immersion circulator. I’ve toyed with the idea of buying one for a year or two but couldn’t justify the $200 price tag while wondering how much I would really use it. There’s a lot more competition and prices have come down but are the low price units reliable, provide constant temperatures without sounding like a jet taking off. Many of the units have Bluetooth and wifi. Are these essential options or just add ons that drive up the cost?
