Things I liked:This is a fun bb pistol that can go through a lot of BB's quickly. Be sure to get the conversion so you can use the large air tank and save yourself a lot of money and wasted time changing out the air cartridge. Why spend your time doing anything but shooting. I like this thing so much I am thinking of buying another so I can double fist it. I whipped this thing out at a birthday party and it was used for hours and hours until it was time to leave. I loved it the kids went nuts when they could get it away from the adults. Things I would have changed:Over all its great but I do wish I could fire more rounds without pulling the trigger more than once. it takes about 3 trigger pulls to empty the clip of bb's I would like a hoper that holds 300 rounds that could fire with one pull of the trigger. I would also like to see a longer conversion tube so I could carry a tank on my back or on a belt like you do for paint ball guns.The larger tanks last quite a while so don't scrip on the few bucks it costs to it. you don't buy a Ferrari and put cheap race tires on the thing. What others should know:the conversion is great but my bottles tend to blow out the rubber seals quite often so you may want a couple of tanks just in case you loose 1 or 2 seals the air is lost when this happens and even if you save the tank and most of the air you cant use it until you replace the rubber seals so carry a couple of them with you.
Things I liked:This is a must have for any gun that can use it, saves time on loading cartridges. This thing gives you more fun and saves money a win win for you. Things I would have changed:I would like the hose to be longer so I could hook this to a scuba tank!! or hook it to tanks on a belt used for paint ball air tanks. What others should know:You are wasting time and money if you don't buy this.I don't want to be overbearing but unless you simply don't have the money you really need to get this you will only be cheating yourself if you dont.
