Review: Fits and works well. - It fits the phone and works well.
Review: Inexpensive, works perfectly in totally satisfied ! - These batteries or for my cordless telephones. I have bought several batteries over the years and have always been satisfied with them. If you attempt to buy batteries for your cordless phone you will find out in many cases it's cheaper just to buy brand new phones. The best way is to buy new batteries from desertcart. I checked with the big boys on the block, you know who they are the big blue and yellow signs on the front of the building. They wanted as much for batteries as I could have bought brand new phones. These batteries are inexpensive and last for a very long time and saves you the money and expense from purchasing new phones that you really don't need.
