Input:
I've been using this now for about 4 months and it works great. I use it mostly just for making meatloaf, but it is very convienant because I can make whatever size meatloaf I want and don't have to worry about figuring out how long to cook it for. Every meatloaf turns out to perfect doneness...this product does exactly what I wanted it to do.
