How long did they last before they did not work?

They were still going strong (6+months) before the garden shear mis-hap that cut the cord.

I just bought them about a month ago and so far no issues and the kids love them

Out of the 3 pairs I've had, 2 of them lasted less than a week and one lasted only a few weeks longer.

As long as you cleean them properly they last. I have had mine for 2 years, just brought em out last week for a project and works great. Just be sure to properly disassemble and clean them and thes are a fine investment

mine lasted less than 7 months / 10,000 miles. I was really disappointed because I liked the bulbs when they worked. I contacted Philips customer service and they told me tough luck. I've vowed to never buy Philips again and to share my bad experience as often as possible.

It has been awhile, but I recall that mine only lasted about 2-3 years. I don't know if that is typical.

I don't know, but they should have lasted longer than that! as you already know.

None at all. They have worked just fine. I had them installed in late October I believe.

I have used them about 5 hours a week and it has been 2 years and 9 months; they are still working. Just remember when installing them wear gloves.

I am not sure how long they work maybe there was a surge in power. That caused it to not work so well anymore. might be helpful to put it on a surge the next time you get one.

They are supposed to work for about a year. My last pair lasted about 13 months

I don't know how often you use them but I have had some for up to 6 months and haven't any trouble with them. Hope this has been helpful. Thanks Bert

It all depends on how long you are utilizing them. I've only had them for a little over 1 month and they are working perfectly.

Mine are still working, had them almost a full year. After about a year's worth of continuous use these type of batteries start to go south. If you've used them regularly enough this may be the case. Occasionally there are defective products however.

These didn't work period when I got them. They went right back to the vendor. I don't have any idea what must have been wrong with them either ?

Apparently a year is about the programmed life of these tag pens. Mine stopped working altogether shortly after.

No, I have not. And so far, I have not had any problems with them lasting for weeks and even several months.

Can vary greatly. Mine lasted less than a year. But also had some that lasted two years.

Don't know, I haven't had to replace them. But it's my understanding they last or thousands of hours.
