I have some expierence with the mosquito I purchased one for my wife a couple months ago. She preffered the feel of the grips over the walhter P22 (which is what I wanted) but it was for her. We found that the Remington 22 Thunderbolts with the heavy spring so far is the way to go. I tried roughly 5 different brands and they just did not seem to work various problemswith ejecting and reloading the next round CCI's were the worst. All in all she loves the gun!!!
