anyone have experience with these LED lightbulbs?

I've been using the Cree bulbs from Home Despot. To the point that when a CFL or perhaps incandescent goes poof, the fixture gets a Cree. I like the idea that I should never have to replace one, and that if the kids forget to turn off the lights, I don't really care about it.

In fact the daylight bulbs are notably brighter, and were installed in vision critical areas like the kitchen.
