This is a must have product especially if you have a laser pointer. I have tried another brand but this brand seems to be lasting a little longer for use of. The product comes in a convient size package and there isn't a struggle to open it. The only negative i have is that they are not easily found on store shelves.

Pros: convient size package, easy open

Cons: not easily found in my area

My cats love their lasers, but the batteries are constantly going dead. These batteries are great, because it saves you from buying new laser after new laser. Plus, my cats hate waiting for me to remember that I need a new laser. So, buy a few packs so when the batteries die you are already prepared.

Pros: Must have!

Cons: N.A

a must have if you have cats that enjoy chasing that pesky red spot from the laser pointer. Hours and hours of fun. the batteries last a long time too, so you don't have to constantly change them.

Pros: lasts a long time

Cons: none

we NEED these! we had gotten our laser and the NEXT DAY the bat's were runnign out.

Pros: great

Cons: nothing

If your cat loves a laser pointer, then you will need the replacement batteries.

Pros: needed

Cons: nothing
