I believe the shipment process took too long by today's standards and something that can be improved. The product purchased was the aluminum hard lid for an FTG600 Camp Chef griddle (flat top). The initial lid was damaged on arrival. One corner was bent in a way that would have been difficult to straighten out. Through Route, the shipping support service available when ordering from Ash and Ember, I was sent a second lid. That lid was also bent on all sides. The material is soft and thin enough that it can be manipulated to a point and I spent some time working to get the sides all straight and corners square. The tolerances are so small in the overall measurement that even after the work I did, the lid would not fit the griddle without a good deal of interference between the lid and the griddle top. More work got it to sit down but with some effort. After that, the problem was that the lid did not sit back far enough when engaging the hooks on the underside of the lid against the rear wall of the griddle in the open position. The lid leand forward quite a bit. I really do wish this system worked as it should as the price point of the lid on sale couldn't be beaten. I also do not enjoy making less than complimentary reviews. I did here so others may not have to go through what I did and end up where you started.
