It's not just a top-quality product, but this one can expect for the price either. But he should be able to use more than 3 times. The linkage is so miserable, not left open the screen. Although he locks into place when open, but the slider has such a big game he slips through the barrier and closes again. I had used it just 3 times. This was my second favorable screen but also my last. In principle, I am to blame.
