I have a green non backlit one in the silicone case. It sounds silly but the thing really has changed my life. No guessing. No worries about raw chicken. No worries about dry chicken. No overcooked steaks. By the way my wife has said there are only two things she deems absolutely unforgivable. One is bringing Miracle Whip into the house. The other is overcooking a steak.
So I gues you could say my thermapen saved my marriage.
