Things I liked:It's quiet! The spring mechanism itself is noisy but the discharge does not sound at all like a firearm report. I think this is safe for a backyard in a suburban neighborhood.
It's deadly accurate. Humane head shots on "tree rats" 30 yards away are no problem for this rifle. Things I would have changed:The scope is clear and bright but seems only of marginal quality.. For the money, this gun deserves a better scope I think. The trigger is also marginal.. It needs improvement. What others should know:I started my quest for a varmint exterminating air rifle with a Crosman 1077. It was fairly quiet but the accuracy was horrible and the power was weak. That Crosman is not even in the same league as the Whisper. The Whisper is not only quiet enough for backyard use, it's powerful enough to bring down problem groundhogs and raccoons with relative ease.
I shopped around extensively for the best price on the Whisper and the price from Pyramyd was the best I found. Their service was excellent and I received my Whisper only a couple days after ordering. I'm very pleased.
Thank you Pyramyd!
