I had put this machine to me about a year ago and was not at first enthusiastic. For me, even sluggish bubbles came out even though the fan was quite strong. Then I screwed on the device to the thing to get to the bottom. Des Rätzels solution is that Anstellblech what the air is at the wrong angle deflects. Something over press and even the whole works. Now I have bubbles without end Non Stop. Conclusion: With a little technical skill without major remodeling a super machine, but factory barely usable.
