Things I liked:This scope replaced a $30 Gammo scope on a 177 Whisper, a good rifle but the Gammo scope would not stay on target and at times it was not responsive to adjustment. The Leaper's scope was a refreshing change, with great optics and rock solid stability and consistency. I'm red-green color blind and I could not see the lighted red reticles but the green really jumps out in low light conditions. Pyramid Air staff recommended this scope and I would buy it again. Good recommendation. Thanks Pyramid Staff. Things I would have changed:Place an index line on the light switch so one could be sure that it is turned off when not in use. Again, being color blind, I was unable to tell at the lower settings when the light was switched on. Also, the zeroing in figures in the manufacture supplied manual are poor quality, small and poor resolution. I contacted Leaper's staff and while they were very responsive to my e-mail request, the pdf manual file was no better than the one that came with the scope. What others should know:Everyone says it and I didn't do it until I got frustrated zeroing in, read the directions!
Things I liked:Accuracy,pumping power, durability Things I would have changed:The cocking mechanism is tough even for adults. My grandsons ages 8 & 11 are very strong and were able to pump the rifle but the 8 year old really struggled to cock the rifle and it hasn't got any easier after 250 shots.
