This product with the magnetic closure is not bad for the price. The problem with the clamping rail did not occur to me, and I have not cut myself.
The screening was with me just, I could substances along the pattern cut, so that everything looks fairly straight.
For the price it is ok, for installation it is better if you do it as a couple, alone it is not feasible.
Let's see how it proves itself in the summer ... will be my assessment also adapt accordingly.
