4 Pack LED Armband Running , High Visibility Wristband for Runners, Joggers, Pet Owners, Cyclists, Adjustable Waterproof Reflective Bracelets for Night Running, Walking

I've had the rechargeable battery types only to find those batteries last about a year, then throw the band away. This product has a simple non rechargeable battery, replace battery or go to the next band. we've used similar ones at trade shows and they will last many years on the same battery. You receive 4 in the package for many years or give some away for this value.
