USB Missile Launcher is an unusual and certainly not common gift idea with the most, even older, have fun are. However, I think that this device especially male buyer finds; D Now for handling: how to install the device driver takes sortware Not even a minute and even goes on Windows 7! the device is detected quickly and is ready for use immediately after the 3 have been (not included) inserted batteries. The software is simple and the operating concept positively, so there are arrows for direction and a fire button with sound effects. the first taste of rocket launchers worked just fine, but the range of the missiles is not the greatest and it is troublesome to put an end again. However, the range sufficient office desk to ask loving times the neighbor on the other under attack. to build quality: it cracks a bit when turning and most of the biggest criticism: see the arrows to 5x times will recharge very battered and have no high quality and durability on. CONCLUSIONS: the relatively cheap USB Missile Launcher is a nice fun for the office to its neighbors times to annoy a bit. Aleerdings the quality is low and it is not intended for home use, because it is there boring and nonsensical. also makes the device only in the group useful !!!!! I would also recommend the device to youtube time to take a closer look, so that no misconceptions are awakened;! D
