Using this product, our team found that the batteries drained quickly and required frequent replacement. The alkaline claim did not deliver rendering this product unworthy of its price tag. A pro is that the batteries were easy to install... A con is that they are not dependable, causing frustration and inconvenience. As a health and household product, it`s imperative to have reliable batteries for safety reasons, which these batteries did not provide. Overall, we do not RECOMMEND this product..See full review
