This is my second LEIFHEIT roller door. I bought the first in April 2009: easy and convenient to install, easy and convenient to charge, easy and convenient to use. 2 adults and 2 teenagers to use it for 4 years and 2 months almost. So solid! but provided to refills properly: for paper: all brands have the same product with different decorations. For the transparent film it is better not to exceed 25 m refills and choose the quality for the roll unwinds easily. The same applies to the aluminum foil (a 40 or 50 m roll "fluff"). For the service, the place and won aesthetics .... (!), "The price is really moving well" !!
