This Review Title is Works great! and the content is: Grandma's no longer with us as of 6-2-10 but I used this product daily to keep her $5700.00 hearing aides in the best shape possible. If you spend any amount of money on hearing aides, you want to protect them from moisture and this product is a must have. You can't use air in the can because it could frezze up the parts inside the aide(s), so this is perfect!.There are other information for this review, one is This reviewer did purchase it and the other is 3 people think this review is helpful.
