The fly screen itself is really useful. But were also with my order - as in the case of previous reviewers on this site - 4 of 5 mosquito nets supplied in the wrong size 100x100 cm, although in each case the ordered size of 130x150 cm has been reported on the packaging. A fly screen also looked as if it had already been trimmed by hand, frayed at the edges. @ Amazon: Honestly, I do not understand. Where there remain the quality control as well as an adequate appreciation of the feedback from purchasers, since it is permanent but prompted by Amazon to evaluate products and packaging ?! Of course, I am delighted that an equally friendly and competent staff member the necessary redelivery and reimbursement documents mail me, but also means that an extra effort. And the required flyscreen I still have not. Pity!
