I took the version 100-700 mm ... The machine is rather imposing but I must say that at first seemed very slender, lost everything he had in his enormous carton! In my opinion Amazon can make significant progress in the optimization of packaging. For now it's still often oversized, so it's a waste. Anyway the attached greenhouse is doing its job and I find it quite convenient to handle. In fact, at first, the moving part is not slid very well. But she quickly "run" and now there is no need to force to adjust the spacing before the actual tightening. Good material.
