"Satisfied"
"Battery worked well in a Timex Expedition watch."
"I bought these at less than what ONE cost at Walgreens, which went dead within 2 wks. ! So far, going strong in my clock radio which only needs this for the clock when power is off. I highly recommend Battery Junction for your battery needs."
"Best and reliable"
