Works great!
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!
