My personal recommendation

After me, I perused several customer reviews, and I had put off something that the alleged "cheap products", I chose the product of tesa.
And I was not disappointed. Thanks Premium Shipping flying network including fastening strip was there the next day and within less than 15 min. hung the network in the window - without any problems.

I can not say anything yet about the durability of this product, but that's been already noticed:

1) super quick and easy installation
2) almost invisible (inside)
3) no meshes error
4) very fine meshes (loosely holds flies, gnats, and large to medium-sized mosquitoes)

All in all, I find that this product has a very good value for money and is profitable output.
Already have an additional power for another window ordered)
