Yes, you need a new one. 23 years is a long time. I think you got your money's worth.

I've purchased mine a few years ago and still good for me and was regularly used. I have not replaced so far.

I don't believe so. This stuff appears like it will last quite a while before replacement will be necessary.

No, you will need to replace it with a new one. But depending on how heavy the use is, one can last at least a year.

Mine was for at least a year into the future. Other than that I have no idea--ask the Seller, I'm just another customer here like you!

My recent purchase has almost 2 years remaining, so the product probably has at least a 2-year shelf life, could be more.

Depends on the manufacture date. Typically, the stuff I purchased had a solid 10 years on it.

I have an older version for more than 8 years, use it at least 10 times a year and it works perfectly. I would contact the manufacturer asap and make lots of noise, politely of course, since you have the option of reviewing the product online at various sites including Amazon - that should get their attention.

Had it for months now and I think it is supposed to last for years. First time it was changed since bought. That's probably 10 years.

If you check the back side of the unit you will see a label which has various pieces of information including a manufactured date. I quite sure you'll find it is probably six or more years old. That being the case, the unit must be replaced. It's useful life has been reached. It is designed to be this way. New batteries will make no difference.

I wouldn't worry about the picture. The product will have an expiration date on the package. The components do have a defined lifespan, after which the unit should be replaced. It's a very easy installation.

A LONG time. It was years before I had to replace mine, but I don't use it every day. Maybe a couple times a week is all.

I have had mine for about 4 years with no problems. Every so often I will buy a new one just to be on the safe side.

Have not had to replace mine yet and have had it a long time as well. You should probably contact the company directly or do a google search for it...

Most manufacturers say 10 years is the recommended life span. In my experience the units I replaced with this product lasted just short of 10 years. So keeping this in mind, if you are within 8 to 10 years, replacement of the current units is a very good idea. Hope this helps.

You can expect about one year depending on enviornment however I would wait till the original goes before buying a new one
