Yeah, already changed my life, too. Because they're made in China, I don't trust them anymore than I do toys or pet food made over there. So, I don't leave any lights on for the pets when I go to work, and have to walk in the dark to the car. I have not noticed my electric bill going down one red cent, despite having CFL's and turning them off when leaving a room. And I can't use them in 2 installed fixtures and 2 lamps, because the shade/globe is shaped to clamp onto an incandescent.  All minor points that build up to a big irritant. 

And how many people out there do you think will not just pitch the used bulbs in the trash bin? 

On the other hand, work just replaced half the lights with LED's. Wow! Pretty, shiny! They're installed with a motion sensor, too, so it's like walking down a fairy path. Those lights make you smile. ;)
