Pros:
Looks great on the shotgun, legit, tactical look, fits perfectly, allen wrench included, size and shape of light are perfect, on-off green color button can easily be seen and reached while holding the shotgun, rechargable battery with good Ah rating, wall plug-in charger included with charging indicating LED, adjustable beam going from wide to a small brighter scanning square just by pushing out, or pulling in the light's front.
Cons:
The brightness is not even close to 1200 lumens as advertised. It is more like a bit below 500 lumens (but still does the job).
I would recommend this product.
