Query: Great for dealing with delicate foods or re-warming on a gas stove.

My girlfriend has a gas stove and has had problems with burning things when simmering sauces or re-heating. I gave her this and she gave it a try and absolutely loves it. In fact, one of the first uses she had started re-heating something and we went off and got distracted and she rushed back when she remembered only to find that the sauce was fine -- no issue with burning. Previously, she would have had a charred mess in the bottom of the pan.The only down side is that the handle "locks" in place and where it mounts is fairly flimsy. She couldn't figure out how it worked when it arrived, but that was because someone had opened the handle up and then folded it closed, without releasing the lock. The metal of the diffuser folded. The locking mechanism is fairly aggressive and a bit hard to deactivate with one hand.It does smell a bit when first used, the shiny coat burns off. But, it works great and was very inexpensive.
