First impressions of the SousVide Supreme

I used to be a chef and have seen Sous Vide working in restaurants, so I knew what to expect. When I got the SousVide Supreme it looked like a big deep fat fryer. I was pretty disappointed as I'd spent £400 on it and the Andrew James vacuum sealer! 


A lot of people on the web were saying that they'd converted a rice cooker etc for £10 so I was starting to think I'd send it back and try the cheap method! 
Maybe I'd send it back after I'd tested it?
It came with some strange metal bits inside that look like a toast rack and a bottom tray and another bit that I'm not sure of the purpose?
