Things I liked:Great Finish on the product, does not have a cheap feel or appearance as a low cost product sometimes does. After just a few minutes of shooting once installed on my custom air pistol I was rewarded with great accuracey. Great scope for an air pistol. Things I would have changed:For what it costs, whats there to change? What others should know:Pyramid Air is a great place to do business with. Have had great experiences and customer service is top notch.
