Bought these a few weeks ago, no dead bulbs on arrival and it's held up until now. Usually with cheap brands at least a few bulbs burn out super quickly, so I'm happy that they're holding up.

Bulbs are bright but so far 2 of pack of 16 have gone bad after only a couple weeks. That is disappointing, I have HUE bulds going on years now without issue.

I've purchased at least a dozen on these over 12 months or so. More than half the bulbs have burned out. I bought replacement bulbs and half of those have burned out. The old Edison bulbs lasted longer and despite the higher energy cost would have been cheaper in the long run.

Bulbs don't last very long so you'd better put into account the price of buying replacements quite often.
To be clear, that's the case with the ones we use everyday. I have another set that doesn't get much use and only 1 bulb is gone.

One of the the lights went out after being on for a few minutes. Love the cheap price but I won't be happy if these have relatively short lifespans. Lights up well. I have only used three out of the bag for the past 2 days so hopefully most of the rest aren't defects.

Bought these as a spare for when the first set I got goes out I have a spare ready to put in great lights but as all bulbs do they don't last forever so I'm ready.

While I will be glad when we have bright LED bulbs, I am also very glad that I can still get these incandescent ones and that they are very bright for reading. The only drawback is that they seem to burn out relatively soon.

One of the bulbs closest to the USB A plug is already burned out, but the rest of the lights still work and it still charges my devices.

A great deal for replacement lightbulbs for your items requiring this type of bulb.  I replaced one bulb on a bathroom light fixture one month ago and the bulb has already burned out.  Not sure if it is a bulb or fixture issue and will update if I can figure it out as these bulbs should be lasting much longer than a month.
Update March 2015:  Must have been a bum bulb.  I replaced it and it hasn't burned out since and neither have the other 3 used in this fixture.

I have 6 of these bulbs in my rental cabin. I replace two with the bulbs from this box and they both worked fine. I've had them in for a little over a month and they are still working. They come well-packed and there are enough to last me for  long while. If you've bought them at lighting stores before then you will know they are a bit on the expensive side when you buy them singly. These seem to be priced much lower.

This is a good price for a pack of 6, considering how expensive these bulbs are at retail stores. I was originally going to write a bad review because these bulbs were blowing out in a matter of days. After going through more than half of them in less than a week, I realized it might be the light sensor on my fixture that was causing premature wear on these bulbs. After a while one of them wouldn't even turn on after putting in a new bulb. Finally, I got the idea to bypass the light sensor and all is good again. So in the end, it wasn't the bulb's fault. (Side note: there is mention on the back that these should not be used with photocell light sensors. But it's odd because this type of bulb is pretty unique, and I had no other option)

...I thought it was odd that they were burning out so quickly, because they're the same brand that I had bought at Home Depot for the replacements before, which lasted much longer. I'm just happy that I shouldn't have to be burning through bulbs so quickly anymore, and I would buy this 6 pack again when I need replacements.

I have these lamps that are not super stable but are rather stylish.  As a result the lights themselves sway back and forth from being bumped into, moved or cleaned.  Normal filament bulbs break after about a week or so of use.  These bulbs are bright and don't break easily lasting months and months.  I know my situation is probably not common but you should be comforted knowing that if they hold up in my house, they will hold up for you!

I was happy with the appearance/performance of the bulbs but just had one burn out in less than a year.

The light produced is a bit more yellow looking than the Xenon bulbs these replaced, but they still look good and don't get hot like the old bulbs.  As others have noted, they flicker quickly at the low setting on my under cabinet lights, but this isn't a problem because we have always only used the high setting anyway.  Great to save so much electricity and I hope they don't burn out as frequently as the Xenon bulbs did.

9/5/18 Update: 2 bulbs out of 7 in use burned out after just over a year.  Seller gave a partial refund.

But then they start to fall apart and look shoddy. Then the batteries die out. But before that, either a bulb blew out or the whole thing stopped working.  I'll see if I can replace the bulb.  Not as bright as everyone is saying, especially if you hang them above a door.  But, they put out a decent amount of light.  I like these lights, or I should say my hopes are still high for these despite getting dashed all the time.

These have been in use now for about a year.  About half of them have burned out already, and they don't get used very often.  While they are a good price, they definitely are not the longest lasting bulb out their.  The color temperature of them is good.

Bought 2 sets of 6, needed 8.  None arrived broken, but one did not work at all, and one blew out the next day, so I'm really wondering if they will last anything near the 7 years promised.
I am however thrilled to find CFL's that both fit in my small (maybe 12", 2 bulb) overhead fixtures and give a nice amount of light.  Previous attempts either resulted in cracked bulbs as we tried to fit the fixture cover around them, or those that were small enough to fit, gave out so little light that my dog was asking for a seeing eye dog.
So, even though the power use savings is probably negated by the dud bulbs, I would be pleased if these last a few years because they give off great light, and not having to change the bulbs in the tricky overhead lights for years would be worth the cost!
