Bests & Worsts Reviews from Amazon

I bought this two years ago. I really liked it at first, sans the dripping fat down the back, and I even purchased one for my daughter in college. After about a year, I found it didn't sear near as well as it did when new. The last time I used it, I made two 1/2-in burgers. I pre-heated it on high for 15 minutes - it ended up with a semi brown mess. I have since thrown it away. I never said anything to my daughter about it - she called last week and said, "Mom, I hate to tell you this, but I don't much like this unit." She had the exact same problems. Shheeez - $200 down the drain. Now I'm searching for a replacement.
