Product very well thought out, there is provided a cleaning cloth for the window frame, a cutter, the adhesive Velcro roller and the net. The screen filled his role perfectly except that it does absolutely not take up the adhesive slips as if the glue is liquefied with heat, result, mosquitoes and other flying insects spend a straw! I do not understand the positive reviews for this item, Also if you need paste the adhesive against the doorframe and not the seal tower frame, make sure that it does not clog the vent obstructions. I am very disappointed with this system, not reliable at all on current pvc windows. However, and it is to report, after contacting Amazon, its sav is perfectly flawless and well beyond my expectations, it's very serious.
