Bests & Worsts Reviews from Amazon

This is my first Cuisinart purchase and will probably be my last. I have used this Griddler Five two times now to grill steak. Both times I tried to use the SEAR/450 setting. The steak is suppose to sear for 2 minutes and then revert back to 425 degrees, cook for 2-10 more minutes depending on degree of doneness. After the 2 minutes of searing the unit DID NOT revert back to 425; it continued to cook at 450 and almost totally ruined my steaks. Tried steaks again on another day; same thing happened, tempt. remained at 450 after 2 minutes. Was prepared this time; turned unit off and then on to a much lower temp. I called the Product Inquiry line at Cuisinart and after a very long wait finally spoke to a service rep. She quickly admitted she knew nothing about the new Griddler Five, knew nothing about the sear/450 function and told me just not to use it. Say what?????? I then sent an email to Product Inquiry Help, detailed the problem and mentioned the service rep. didn't have a clue about the product. More than a week later I got an email back asking for the same information I provided in my original email which was shown below their response. I am more than frustrated with Cuisinart and this product. I'm toying with the idea of returning the Griddler 5 because it might be defective. I just don't know. I guess the unit will be fine as long as you don't use the SEAR/450 function. UPDATE on 9/21/18- I recd. another email from Cuisinart. They are sending me a new unit to replace my defective one. Hopefully this one will do the SEAR function as advertised. UPDATE on 9/28/18: The replacement unit from Cuisinart doesn't work any better then the first one. SEAR/450 not functioning. To add insult to injury, I have to pay $24.00 to send the first unit back to Conaire. I will NEVER do business with this company again. I've changed my rating from 3 stars to 1 star.
