This seems to be the best price I have seen for this sous vide cooker. This is the bluetooth version. The Wifi is also available at £149.
Bluetooth (UK Plug): Serves 7-8; Connects to your phone via Bluetooth, and allows you to start, stop, monitor your food, and receive notifications when you're within Bluetooth range.
Please vote based on the deal itself and not if you like sous vide cooking :-)
