the quality on this is so good and everyone in the office loves it!! the quality is so clear!! i love this product and cannot recommend it enough!! so good!!

They lasted me a long time, so would say they are as good as the rayvonac extra batteries. Would buy again if a bit cheaper.

I've been using this brand for years. I haven't used any other battery in those years. I like the packing the most. I throw it in my purse. It's easy to find in my bag and it stays closed. The batteries are easy to change. The batteries last the same about a week and a half for me. I have worn size 13 for about 25 years. I can rely on this battery. I buy on sale though.
