They're very good little .22s, and I've never seen one crack that wasn't badly abused first.
Better than that, they are the absolutely perfect 'first' gun for kids - they must be cocked by a very definite, separate action before they can be fired...there is no doubt whatever whether it is safe or not. They do not #### simply by closing the bolt, as do most .22s.
As far as I'm concerned, they are better by far than the much more expensive Chipmunks, and the like....and you'll never shoot one out in a lifetime if you find a good one and look after it. Most shoot very well indeed.
