Have the Berlan greenhouse last week finally built in the garden after it in the basement had to wait for better weather 2 months Building I found relatively easy, after about 30 minutes standing the frame. The application of the film was easily enough since air between frame and foil. The frame is made after it has been completely assembled, without the film relatively stable. I have the frame after assembly of the terrace carried into the garden without which it has moved here. The film is well made in my opinion. How good it really is time will tell.
My conclusion, for the price a strong buy recommendation.
One point deduction is only because of the assembly instructions. This could turn out really somewhat more extensive. For me it was not a problem but not so technically savvy buyer could even despair.
Update after 2 years. Unfortunately, the film begins to dissolve itself. It is in several places the holes are already so porous emerged. Seems not to be UV resistant.
