Awesome price!  I was also skeptical to buy "cheap" bulbs, figuring half of them wouldn't work or there would be some other defect or problem with them.  I'm happy to report that I installed 10 out of 12, and all 10 worked perfectly.  If they burn out in an unusually short time, I'll report back and update this review, but for now I'm incredibly happy that I saved a ton of money by purchasing these bulbs.
