Pros: Very bright LED's. Nice, well pronounced color. Puts off little to no heat so they are very case friendly.

Cons: The adhesive is garbage, so that earns one less egg. Might as well buy some crazy glue or tape; or get creative with your cable ties. These things stick so well I had to open my case every night or two after work to re-adhere them.

Other Thoughts: I'd buy again if I needed to; but if want them for backlighting your monitor or want to stick to an inverse surface, like the ceiling of your case or under a desk; then bring something that will hold better than what comes stock. You'll need it.
