I may have purchased these about 7-8 months ago. It has been so long I forgot where I got them from. I wanted to try them out before reviewing them due to the price and how many are in the package. I must say, I replaced the batteries in the ear wax pik, and the kids talking books and put the rest up. At this point the batteries are still going strong and I have no idea where in the world I put the rest of them to take a picture to add to this review. I am actually shocked that I have not had to replace any yet. I wanted to ensure that I gave an honest review on these as far as life. To be so long that I forgot I needed to review them, I will say is a great product lol.
