We have this power now hanging over our bed for over a year, and are really happy with it. Finally sleep soundly without worrying about annoying mosquitoes! One should, however, at the head of the fabric fasten somewhere (with us it's tied to the bed frame), so you do not have when sleeping on your face the net when one lies close to the edge.
After a year of constant hand you can already see now some Nutzspuren - the seams above, where it is moored, begin to dissolve. But this is easy to fix and therefore not a big problem.
