I purchased this product based on reviews on the internet. One main positive comment was that unlike other griddles, it distributes the heat evenly. I have bought this mainly for making pancakes and followed the manufacturer’s instructions to preheat for 8 minutes at 350 degrees then adjust to 300. Unfortunately it has been a big disappointment as it keeps burning my pancakes based on manufacturer’s settings. At 350 degrees setting after 5 minutes my laser gun thermometer indicates the temperature at more than 400 degrees. So, I am going to try to start at the lower setting such as 300. I am not into habit of returning products after I’ve used them. Otherwise I would have done so.
