Used for the first time last night.  Made sliders for the kids...  based on the instructions on the included booklet, I pressed down for a few seconds and then cooked for a couple minutes.  Came out great.  Issue I have is that the green light never came on to signify the grill was ready.  Plus, on my old grill, there was a pre-heat dial (similar to a 'toast' dial on a toaster) that showed you the grill was pre-heated after five minutes.  The dial also showed you how long to cook different types of food and had a much larger grill area.  With the Cuisinart, you have to figure out how long to cook.  Also don't like the grease collector which is at the BACK of the unit.  Felt like it was going to get too full, and that I was going to drop it on the way to the sink.  My other grill had a much larger grease collector on the side... Just wish I could remember where I got the old one!!
