Query: George Foreman XXXL Family Grill

I purchased the above identified grill from Sears on July 25. I am very unhappy with the grill. Food placed on the grill slides to the bottom, and the lid does not adjust to cook all food evenly.I purchased the grill after my brother told me how he was enjoying his grill; however, his grill has a timer and apparently is a better product than mine. The price of my grill and his, however, was [price]--no difference in price. I did not see a grill with a timer.
