Comes with original box and manuals and charging cable, interior pads are used.680nm1 year old, used it about 4 times a week, the battery is still very good and holds charge for 3 to 4 uses. The battery can also be replaced easily. The lights are rated for usage in the thousands. I did see results with hair thickening, but I’m getting FUE so I don’t plan on using the helmet anymore.
