anyone have experience with these LED lightbulbs?

Note that those aren't omnidirectional so will not be useful in many fixtures. Also, they are a no-name brand with no warranty mentioned and are about the same efficiency as better quality 40w and 60w Crees from Home Depot. Sure, they're $5 cheaper each, but does that really matter for a product that you are going to keep for a decade and that will pay for itself in a couple of years?

Edited to reflect price is for a 2-pack as pointed out by Black.
