The greenhouse consists of a metal rod with plastic connectors and a slide. I think for the price you just do not get anything More stable. The film is without reinforcement (except of course at the edges / corners). That is why it is in our half-protected by a few months and a hailstorm ripped something. Good fixing by tape is back up. This lends some stability. The three holes on the upper film are as already written a bit inconvenient because the water falls straight down there. Otherwise (shutter, etc.) everything is OK.
