It's a nice screen, works well as advertised, but caveat emptor, the supplied concrete screws say they are supposed to be 10mm and use 10 mm masonry drill bits, and I couldn't get them installed with 10 mm drill bits. Instead I had drill 12 mm holes, to make room for plastic sleeve that accompanies the screws. You should be very careful about installing screws that are removable if you live in an HOA or have a landlord with restrictive policies.Another problem is that in the US, metric drill sizes are not easy to find, as everything is in inches, and the size you need for these screws is larger than 3/8" but less than 1/2" dimension. That means you can't use US drill bits because the nearest sizes would be too small or too large for the supplied screws. Also even worse, if you did buy 1/2" or 3/8" inch cement screws, they won't fit in the metal brackets for each pole because the holes drilled into footings are just too small. Thus I was stuck with a 10 mm hole, that required 12 mm drill bit to make it wide enough for the plastic anchors and allowed the concrete screws to be tightened.Thus the only real way to install this system is to use 10mm concrete screws, with the supplied plastic inserts, but be sure to pre-drill a 12 mm hole (not 10mm) because the 10mm hole just won't allow the screws in.
