### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great!
  

*by S***Y on Reviewed in the United States on August 9, 2016*

Good batteries that last a long time.! I wondered if the batteries were fresh and they were. They have an expiration date of 2018 (two years from now). These batteries last a day or two longer than the more expensive ones we were buying from a big-box retailer, so we are very happy.

    Just what I wanted

So far its a lifesaver.

    Battery life
  

*by R***  on Reviewed in the United States on May 16, 2021*

Much better usage life over cheaper batteries, at least four more days  depending on length of time in use. Clarity of sound is about the same. I will use this brand from now on.
