EZ Red auto memory saver.
I used the EZ Red auto memory saver for the first time today (2-9-26). It worked just fine. The instructions on the back of the unit. After changing the battery I noticed that all of the memory was still in tact and everything worked perfectly. I am very pleased with the EZ Red memory saver and I highly recommend this product.
