There was a time when you could get these (different maker) at the dollar tree. Oh how I wish I had stocked up. These are a close second in value and they work great. I bought two sets to store back-up kitchen towels bought on clearance so they stay new and fresh and not dusty. It has been weeks since is rolled them up and they are still compressed.

These last quite a while. It seems the originals work better vs the less odor ones.

These worked have worked well so far. They fit into our previous mounts around the house. Now I am hoping they last more than a year or two unlike some of our previous detectors.

I have been using a couple of these for several years with no issues what so ever.

I have used these batteries and charger on every trip I have taken since receiving them.  After several years of use they are just now not holding their charge as well but still work.

These work well for an inline filter for the icemaker on the fridge.  I've used this method for about 15 years and change them out about every 6 months or so.  I'm glad to see them still working.

These are easy to install and still work very good after about a year. There is no sign of them getting week or needing adjusting.

seem to keep long charge.

I've recharged each about 5-6 times in short period ( from heavy use)
and they hold up
