Things I liked:The noise dampener worked quite well but not as silent as i was expecting. The open sights as well as the included scope was easy to install and easy to sight in.Love the color. Things I would have changed:The trigger is a bit heavy and a little bit creep of spring when cocked, i wish they would add sling stud or swivel on the Whisper. What others should know:My Whisper was not picky on ammo, i shot Benjamin Diabolo 14.3 gr, Beeman Crow-Magnum hollow-points, Gamo Hunter and almost any kind of pellets in my arsenal, except for the Gamo Magnum 15.89 gr., i got a couple of fliers at 40 ydrs. The Whisper prefers dome-type heavier grain pellets at longer distances.The Whisper is freakin' accurate !!!
