I love the Wi-Fi model - been using for about a year. A bit finicky to initially connect with Wi-Fi (may be due, in my case, to using Google WiFi with 2.4 and 5ghz bands having the same name - mesh sometimes confuses devices that can only talk on 2.4. once it was connected though it's been rock solid ever since.
I love being able to monitor and control the process remotely. The device itself is beautifully made. I've since added a form fit zipped neoprene case for it, a blow torch (MAP/plus gas) for browning, and Santa just brought me an excellent vacuum sealer to add to the mix.
No regrets - very glad I got this model.
