Query: Good idea, poor execution

I was very disappointed with this griddle - ended up returning it. Putting pancake batter on the cooking surface cooled it by almost 100 degrees (according to my IR thermometer), and it was very slow to reheat -- resulting in badly cooked pancakes. It appears to me that the removable/washable cooking surface means the temperature sensor isn't close enough to the cooking surface, so it reacts very slowly to changes in surface temperature -- it takes a few minutes before it even notices that the temperature has dropped and turns on the heat.I was also disappointed with the size. Too narrow to cook medium sized pancakes side-by-side, and too long to conveniently fit on my counter. Shorter and wider would have been a better choice for me, so that's what I'm looking for now, although I would have kept this one if it had done a good job of cooking pancakes.On the good side, it did an excellent job on a grilled cheese sandwich.
