Yes, I would buy something that cooks perfect steaks, but not that thing. Buy a "Sous Vide", it works, and it works better than you can believe.
I was actually against it, my wife bought it, first bite changed my mind. Every bite since has been perfectly as good. You almost can't screw it up. Eating steak out is now unacceptable, no matter how good the restaurant is.
And you can 'sous-vide' steaks for near zero $, you probably have what you need on hand. A picnic cooler, zip lock bags, digital thermometer. Just bag the steaks, soak in 127F water (more or less depending on how rare/medium you want) for about 2 hours (time is not critical at all). Sear in a very hot pan quickly, or blow torch 'em.
Lots of ways to cook a steak near perfect, grill, cast iron pan, etc - specialized gadgets (like the link on the OP) not required (I already had the blow torch! ).
