Bought two packs of 4 to mount above a large wall mirror in the bathroom. Arrived intact and in perfect condition. The lamps don't hum or flicker and all emit a cool, even daylight color. Edit: It should be noted that the bulbs come with a little card in the box stating that if you email them the code printed on the card, you'll get a free USB wall charger with a night light. I thought it was a good gesture at first, until they emailed me back that my "free gift" would only be sent after I had left a positive review for the lamps and also sent them a review link and/or screenshot. Basically, I was asked to leave a positive review for the bulbs I just received, which means my review will be disingenuous. I took off two stars for those crappy practices, especially since I have no idea how these bulbs will perform in the long run. Also, a USB wall charger doesn't cost shit :^)
