This UV light arrived with the wand, USB cable, instructions and testing card. The wand works while plugged into the wall or with 4 AA batteries. The wand operation is simple with only a single button for on and off. The wand works well and doesn’t have the auto-shutoff that most other wants do when they aren’t facing down. This makes the wand more practical to sanitize objects that you can’t lay flat like door knobs or other vertically oriented items. The testing card shows “disinfecting” when the light shines on the card. The wand is big enough to hold comfortably and the UV light row is long enough to cover most items that you would want to sanitize. I would definitely recommend this UV sanitizer.
