do you know anything about these?

Yes. They are simple screens with net protection to keep bugs away. Pretty simple. Hang it in a dark closet with a fan in there on low and a low watt incandescent bulb to keep the humidity down. The screen off your bedroom window works too. Two work better. Trimmed product on it and lay the other over when filled. Or simpler (like I do) one old clean screen, lay it on there and put in a closet with chopsticks under for air flow, the fan and bulb. Almost free.
 
just curious? why the requirements you have are this exact one.

i doubt there is a dimes worth of difference in any of the same type/style.
