These are very nice. Rechargeable so no buying batteries just plug into a micro USB phone charger that most everyone has so no problem there. Three brightness levels with the multiple pushes of the power switch and a rubberized plug covers the charging port makes this water and dust resistant. All that and they are very affordable making these a smart buy and a good value. Don't wait until it's too late and the power goes out. Be prepared and order today while the light are on and you can see otherwise you could be left in the dark, literally.
