I had gehlt this bubble gun to provide to a party mood which succeeded very well. ^^ Unfortunately, the quality of the toy is not designed to last so I give one star to deliver the whole. All metals used in the gun are not corrosion resistant which just like leads to the battery contacts to problems. In addition, slips through the rotary engine, which pumps the soap, the suction hose into the gun repeatedly so that the pumping action is lost. You can solve the problem by briefly pulling on the hose to make functional again to all. I have the party fun still in operation, and also does not lose its fascination. Especially my house cat has her fun with it ^^ °
