I purchased the same 2 pieces of this gun, even for a bachelor party and even for my 3 year old nephew. The protector of Seifenbalsenfläschchens been going down really difficult. Then there is the further that the gun only sporadically prodoziert bubbles. Luck has it only that there is a Laugenrückfürhung. The liquor, which has not managed to the soap bubble is returned into the container. My nephew still has fun with it, as it brings even a little excitement to the game, if not always come out bubbles. If then times that come, you should not let go of the button, because then come endless bubbles. Have tested the 2 gun, same problem. But at this price no wonder! Nevertheless, only 2 stars for dei function, and one for the optics, because the LED's make a good impression, at least for the bachelor party!
