In my telescopic tube the spring was broken. This could not replace it, I should buy a new tube. The original spare parts was so expensive that the no longer profitable at my somewhat aged model. The new intake manifold keeps well, is stable and can be extended and move back slightly, but this process is a bit strange, because the lock is at the lower end. The "only" 4 points I forgive because the openings are to be there, that you can attach the nozzle, do not fit, at least on my model does not. But that does not matter because the nozzle holds so easily. Conclusion: The suction tube performs its services without any problems and is highly recommended at this price.
