Pros: Bulb Durability, Battery Life, Durability, Brightness
I had an earlier edition, and while the light was very bright and the size is about the same, or smaller than some car key handles, i.e. does not take up too much space. The drawback of the old model was that the case snapped together and would frequently fly apart when I would drop my keys. The additon of screws should prevent it flying apart if dropped and takes this up to five stars.
