Growing already takes a little time to complete. Many small parts that need to be put together in painstaking and fummliger work. Everything still manageable but the main reason why I sent everyone back pleats, the ropes of pleats hang really uncomfortable in the viewing area of the window when the pleated pushed together by the window depends! The ropes are not just like those of pleats on the window frame out long. So for those who value optics, in my opinion is not well advised with this product. Stayed at a hardware store even cheaper than this get pleats and with no great effort growing! Nevertheless, good fast shipping and the refund without any problems.
