We've bought this particular safe dehumidifier on two separate occasions and both times, it looks like the attached pictures, not the stock photo above. It comes with a hook if needed.We placed it in our 1.23 cu ft safe on January 16. The safe is filled with documents/electronics. On February 16, we checked and found that the beads were definitely getting darker, but it could have lasted for probably another half a month. We decided to charge it, to make sure that it successfully dried out the beads. If it worked, we were going to buy a second device (which we did). It took about 14 hours for all of the beads to turn orange again. The device was warm during charging, about the same as charging your phone.
