I bought this clock at an estate auction. It was not running at the time. I installed a new battery, and the clock started running and has been keeping accurate time ever since. About two-three weeks. The battery was unused, but had been sitting for a long time. The clock may need a new, fresh battery in the near future. The instruction sheet and the storage box do come with the clock. The clock does have a push button light. When setting the time/alarm, if pulled too hard, the button will come loose from the clock, but will push right back in. The clock and alarm seem to work very well. The clock is being sold as is, no returns, no refunds.
