This is an excellent product when you use in the oven. It makes it possible to cook casseroles and other dishes that take a long time to bake. And my favorite baked bean recipe turns out even more delicious using this pan. I put some water in each cup just before adding baking soda, which eliminates clumping, and then add my batter. It bakes up perfectly all around - no big globs of liquid left over. The pan heats evenly also, without getting hot spots anywhere.

I bought 2 of these radios and at 1st i was happy with them but after a few weeks the sound became distorted (crackling etc) when playing songs or using in stereo mode on FM. You have to turn both radio's off and back on, then they resume normal. Tried upgrading firmware without any luck, tried multiple frequencies still not acceptable. Now one radio doesnt detect FM radio stations at all, cannot scan for weak signals. A poor purchase!

This band had the potential to be amazing, but they are just terrible. They have no musical talent whatsoever.
