We have the puller 2 times, once for our round shower in the guest bathroom, which is finally free of streaks, as one with the rounding now reached every place (what in commercial straight extractors with handle is not the case) and a rectangular for our shower. The extractor can be added, so it is always ready when you need it.
I am with this Duschkabinenabzieher after 3 years still super happy.
The predecessor to handle that we had did not work, because the shower was not leaving streaks and the puller has made terrible squeaking. This is fortunately not the case.
We use a stripper after every shower, so everything always looks tip top and clean out.
Conclusion: A great product that I happy to recommend.
