Not sure if this is the same product, but looks almost identical.... these things really really flew. Don't know about how the other user(below) was using it .... sounds like he was trying to sit down and use it like on the diagram... works a lot better with two people holding the ends and another firing.... we fired them off our garden and got them in the sea a good 70-80 metres away.... really impressive.
Again not sure if it was this make and model.... But recommendation to the other reviewer try it again like stated above.
I was really excited when i ordered and received this catapult however the excitement soon turned to dissapointment. First of all the 75 included water balloons are terrible. Once me and my friends had filled and tied them up, they just burst as soon as we put them down on the ground. so we decided to buy our own balloons from a local shop and they were much better. however it was then the catapult that let us down as we went to test it out. We followed the limited instructions on the box but just couldnt get it to work. On firing it would get tangled and sometimes come back and hit you in the face. Not fun at all. Out of 10 attempts only 3 worked, and even then it only went 10 metres or so. not as described. Very poor catapult, dont waste your money!!
