Cheap, does what it is supposed

When telescopic tube my Miele Tango broke the spring so I could only with difficulty or not at all off the extract. The original pipe is expensive and difficult to obtain. This product was immediately available and there within 2 days. What can I say: It works and was there still extremely cheap.
The only "problem" / familiarization: the summary is below - ie regulating the length of the brush and not near the top of the handle. I find that awkward - otherwise a good product for less money.
