I haven't had any of mine go bad yet. I have had other lesser quality, cheaper, ones go bad but not these. However, who knows, perhaps the company has been slacking off lately and going cheaper and worse quality?

I have used a few of mine for a few months now, and so far, no problems. I check them with a voltometer before I use them and they have all been fresh. However, only received about 72/100, so Amazon gave me a partial refund. Weird.

I bought 10 about one year ago. One failed after a month. I assume it was defective. The others are still working. That is all I have to go on.

Mine look the same way. If they are working, they are fine. They've doubled in size over a month and work quickly now.

One of the set of mine went out too.... They are "NEW" ones! Not sure why....! Maybe they are NOT really waterproof?!? Not happy with them.

All of mine work so far... But I do look at them as being disposable the last set I had stopped working after a month of regular usage however the price is right and I'll use them as long as they work and then order more.

How long they should work as opposed to how long they actually work... I don't know. But I can tell you that my little rock has been working since before winter. Although I am suspecting that the radius is smaller now, so I may need to switch the batteries.Side note: I keep mine in a ziploc bag to prevent moisture from getting in it. Perhaps this has to do with it? Yes its ugly. No I dont care. =]

I don't know, mine were good for 3-4 months. If you contact the seller maybe they can tell you.

It has been a while since I ordered them; but as I recall that would be about right. The company I ordered them from made a mistake but fixed it FAST and they were very cooperative. Have fun with them!

I bought mine this summer and they are all dead already. They went out two strands at a time. Pretty disappointing.

I havent had any issues, maybe it needs some new batteries, those may be bad. If that doesnt solve the problen, you may want to send it back for another one, that could just be a bad lot you recieved! Good luck

Sometimes they have different dates within the same vendor. Usually the vendor should display them. I didn't have to ask the vendor. The dates were all there at the time of purchasing. Anyways they do not last too long. The larger one was three month

I have not owned it long enough to determine this. They have lasted at least a month so far. Sorry...

I ordered these about a month ago and received three units - none detached from the cardboard. I think someone sent one back and fooled the person in the stocking dept. I would ask for a replacement, if I were you. My three units came attached to cardboard and in a plastic bag. Frankly, I was surprised there were three.

I've had mine less than a month. they serve as my son's night light and they burned out after a couple of weeks. very disappointing as i don't have the ability/ingenuity or time to take them all off and figure out which is burnt out. REALLY disappointing for a $27 string of lights!

Same thing has happend to 2 of our M240's my kids recieved from circut city. So maybe there is a bad batch???They only worked for about a week.

Sounds like a faulty unit, my last one only lasted a couple of months. It's just a cheap fun thing so I figured I would just replace them as they gave out... Since it came that way though I would say return it for a replacement.
