Pros: Least expensive smart bulbs that I've found when on sale. The setup was easy. The app works well. Works well with Alex and Google. Dimmable. Can switch between daylight/cool and warm white.

Cons: Sometimes one will get out of sync with the others. Occasional high-pitched noise from one. (Note that the above problems could be our ceiling light/fan's fault.)

Overall Review: As others have mentioned, the non-white colors are not very bright, but then again they are only 7 watt bulbs. If you only care about the smart features, and the white color and brightness than you will probably be happy with these.

Pros: Works as expected in FreeBSD and FreeNAS 9.2 after enabling USB 3 tunable. It was the least expensive card I could find when I bought it.

Cons: None.

Overall Review: Haven't tried it in Windows or Linux.
