Magnetic windows insect screens

Hi guys, I have seen a video demonstrating the use of magnetic windows insect screens. They apparently do a great job and I would like to ask your feedback and possibly info on where in Dumaguete and surrounding areas to get them.
As always, thanks for your input!

 

I have seen the likes of this available on line perhaps Lazada may be one place to look for this?

 

Yeah, most likely.
Cheers mate!
