I can only agree with the previous reviewer actually. The flyscreen gave me at least about 5 years! And I've taken it at least. Once and once by hand and warm water and then hung up again. The Velcro still holds as the first day. However, I have about a year ago 3/4 (after the last weight loss) is very tightly clamped onto the Velcro tape (as I had originally foolishly cut off in a few places too much). Probably it is now slightly torn in a few places only for this reason. There are however characterized also emerged no proper holes, but you can see just only how separating the thread. I think that you can not complain after 5 years! In addition, I compared times with a cheap mosquito nets from an action at discounters: This was clearly coarse-mesh, thus came there more small insects such as fruit flies or small spinning through. I accounted for under "training money", because now I will probably create something more and I probably again buy the same from Tesa!
