I am 13 and got this toy for Christmas from Uncle. It works very. Generally it works best for two people but one works too. You want to charge it for something like 30-40 seconds, not 10. 10 will do nothing. Nothing at all. The white knob shouldn't really be fiddled with, but occasionally you get a really cool setting where it will go in perfect circles and works great. I thought the trigger was rather lame, it's not easy to press down and hold for as long as you like. Also, charging the duck can be annoying, because it has to be at 0% energy, which basically means you have about five to six flights and then have to wait for it to drain out because it won't work. Despite what the duck originally looks like, it's quite sturdy (I flew it into the fireplace where it started pumping ashes because the wings were flapping, and it still works great). Also, the gun pump isn't the best idea for a pistol shaped gun. Something on the back where your thumb could reach would be better. And even if your duck breaks, the gun makes a good simple pistol for cops an' robbers.
All in all, it works very well, but it could've used a little fine-tuning. What would've made it AWESOME if it was remote controlled by someone else!! That would have been AMAZING!!
I recommend this to anyone who wants to have a little fun. (But it isn't really for older kids.)
