does work correctly
The batteries would bun out after a few days, so I thought the problem was the batteries. I recharged  them several times, then decided they must be defective.  I purchased /replaced the batteries before I realized that the uv light was remaining on and not shutting off. I would ask seller to replace this item but it would cost me almost as much to return it as it would to purchase a new one from another co.and may have the same problem.
