I've had the same ones in for the last 4 months and they are still working great!

I only needed to replace mine at most, once a month. I would say it really depends on if you leave the filter on when you feed your fish. By turning it off during feeding, I could sometimes go 2-3 months before changing it.

I replaced mine when it was not working anymore. Otherwise if it's cleaned well, you don't need to replace it often or at all.

I just replace according to the schedule they provide which for me is about once a month. I forget how to figure it out exactly. I have also read about how to refresh them but never done it myself.

I've used mine about 70-100 times and still no need to replace. Definitely not single-use!

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

Getting a replacement may solve an immediate irritation. However, expect it to become a recurrent one. If you could give the company more aggravation from having to replace these than you receive, then I imagine there is some value in returning this product for replacement.

Keep 'em clean and they should last much longer. I'm at the 6 month point right now and they are still working really well.

I use rechargeables in my machine and they last about a month of twice daily usage (with the 3 averaged readings and some clothes in the way errors with an extra reading twice a week or so.) I estimate that they need replacing between 180-200 individual readings.

I truthfully do not know. I do know that I do not change mine every 6 months. I would think that they last a long time as I have not seen any date on them.

It depends on the usage. I use my when I travel, which is about a dozen times a year for about a week each time and they have lasted for years.

I have been using mine regularly once per week for a couple of months and don't foresee a need to replace them but maybe after a year or so who knows? If I boiled them too long accidentally then maybe that could ruin them and they would need replacing.

They need to be replaced every 4 weeks. Stay on top of it. If there is a root issue at hand that should be addressed through training as well. Also, it can take up to 2 months (2 collars) to see the full effect.

Depends on conditions how well the safe seals and how often your in it, my guess would be 2 every six months. I use two in my toolboxes and change them every six months to a year depending on environmental conditions.

eventually yes, you are going to replace them depending how often and rough you are with them.

You are better off just getting a new one when needed because you have to be careful on how and where you store them. Best rule of thumb is to change them every 3 years with a fresh new battery.
