“I cannot use these batteries because medical problems and advanced age prevent me from using my thumbs which is essential in using them. I can only use the automatic batteries which I love. I know it took a while to get approval from the state of NJ which banned them as being harmful to children. Actually they are more harmful to seniors who are prone to medical conditions which affect our ability to use our fingers like arthritis. I am writing this negative review only as a warning to those with such problems to choose the automatic batteries to prevent further injury and the hassle of returning them. As for Vapor Fi, I recommend them highly and rate them and and the automatics as 5 stars.”
“The quality of these batteries are no longer what they used to be. I've been using them for years. Two of them would not hold a charge for more than a couple hours of use, a third had the manual button jammed into the battery making it unusable and only the fourth one worked as expected.”
