They are definitely a great unit they have only A few drawbacks first their price they are expensive second they eat batteries like crazy you must buy an external battery pack to be practical third they are difficult to aim and miss shots regularly that may be over come with practice and the aftermarket inertia trigger also they are known to be temperamental and break down so that brings their longevity into question and I’ve seen some bad reviews about their customer service But with that being said I still want one just waiting for them to maybe come out with a GEN two model with maybe a few improvements
