You should pay attention only to two things (which should be but really be self-evident):
1. The re-rollers wait until the shade is dry, as this may foxing arise (which we did not try, but just like that)
2. When re-rollers do not be too hectic and possibly hold the blind with the other hand and "lead", so it does not pick wrong (which happens when you simply quickly absorbed).
Taking into that, you really have fun with it and no problems. The design is also nice, fits well into our white bathroom.
