Great little work horse. I have been using mine for almost two years with no signs of break down. It comes equipped with a blue light that changes to red when I charge is needed. USB charger cord included. Remember to dump the water out of your nano mister at the end of every day and wipe out with a paper tissue. If the nozzle becomes clogged, gently rub a paper handled cotton swab over the nozzle and that will clear it!
