how long does it last, does it need replacing after a certain time period?

Good question. I have no idea. No mice for at least a couple of weeks. We wouldn't be able to tell it's broken until its light stopped flashing or the mice reappeared.

We bought two about a year ago. They are still plugged in (just in case a mouse would like to return), the red light is still blinking, and as far as I can tell, they are working fine.

It is a little electrical appliance with no replaceable parts. So I would expect it to last for a number of years.It may not work for mice, as other people have said, but it sure seems to be working to deter roaches in my house.

It is electric. As long as your electricity does. But I promise you, it does NOT work. Mice eat right underneath it. It is useless. Save your money

I'm not really certain. I would think it will last me 5-7 years with how little I use and how infrequently I need to clean it.

It lasts a long time. If you let it go completely out it may last 2 years.I try to change them once a year. And yes it will let you know its low.

From the research I've done it depends on your usage. I've had mine for almost a year. The person who recommended it to me has had his longer. The way mine is installed it's going to be easy to switch out the unit when necessary.

We just replaced our first one after 4 months. Will probably replace it every 3 to 4 months from now on.

I used it heavily for 6 or 8 months, and it's been stored for the next 6 or 8 months, so I can't say for very long term use. However, one of the reasons I chose it is that small parts can easily be replaced, rather than junking the whole thing as you'd have with a cheaper brand. I've also used others' sealers like FoodSaver and I can tell you this one is much better quality.

I don't think you need to replace, just keep it clean and dry after usage and before usage clean again..

I have had mine for a little over a year with no wear and tear. I wouldn't be surprised if the filter lasts for another 2 years. I put it through its paces, using it every other day for a few mins and for extended periods while cleaning once a month.

The owner's manual says replace every year for heavy use, every 2 years for normal use and every three years for light use. I use it only at night as opposed to the recommended constant 24 hour condinuous use, so I think I probably waited 4 years, which was much too long as it was really dirty.

They usually last 2 to 3 years and no u just plug it into the wall and it will start doing its job. That's how mine was also soo I got this one to replace it.

It last a very long time. I'd say years. Even if only a year , the replacement silver is not to expensive. but it should last longer than a year.

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.

I seem to have to replace mine every 18 months or so. Really depends on how much tv you watch.

Obviously, it depends on how often you use it, however. I don't use it every day and it lasted a long time.

No. Should last for a long period of time. Many years if maintained properly.

I had mine for 5 years before replacing and I used it quite often. When it became solid I knew it was time to replace.

If it's been under a year, the company will replace it for you. Otherwise I have one.
