Without taking a 2nd mortgage on my house, this is by far the best unit I have come across. Simple to use, affordable,excellent focus features and not over bulky. Other units led light features tend to blind eyesight temporarily due to brightness. This unit is by far more forgiving.
Pros: 1 unit does work of 2 units.
