Query: Major Assembly Frustration

Assembly of the Airzooka is a major hassle and can be seriously frustrating. Poor product design.From the instructions one can surmise that the user will make the cone out of the three rings by use of a screw thread. The problem is that the thread is on the inside (not visible) and there are two sets of threads (one for each ring intersection) but only one place to hold on - this makes the system difficult to manipulate and impossible to visualize.If you go "off-plan" in the first steps of the instructions it is next to impossible to get back to the starting point: you are on your own to twist and pull, rotate backwards and push. My experience was that the device did not "click" as it should have and the rings got cross-threaded - I then spent the rest of the afternoon jamming it and pulling it until I had something that seemed solid and aligned (a big risk for $18)
