Short battery life is true. Difficult screw connection is true. I suspect that some complaints could be actually caused by the fragile tiny spring that easily gets lost (that part should be available for replacement). However, skillful care makes dry-fire more interesting.
Pros: great for dry-dry practice
Cons: tiny spring on top of batteries too fragile and difficult
