Product review (3 stars): Works.. pero no mucho...
Well, my wife was really disapointed with the gas pans we had on our GE oven (we rent in Washington DC). The building maintenance people told us they could not buy the GE type anymore, so we decided to try this one out.

Does it work? Well, on our GE oven it does and it doesn't! If the pans are small or medium sized, leaving "breathing" room for the flames, it works, but every time we try to use bigger pans we get a gas smell all over the apartment and have to open the windows. Putting it upside down improves things a bit, but not much.

And it doesn't fit 100%, it bounces a bit on top of the oven.

But... we are leaving it on, so I guess it works...
