At that price I don't see these being used much by folks who are trying to make money from their bees. But it's an interesting idea, maybe I'll give it a try!
I have some spare Apimaye "handy frames". https://youtu.be/77SRdnZVsFo They come in two plastic parts that snap together to hold wax foundation. I'm thinking that would be an easier way to install these, and the support bars would add a little sturdiness without needing to bother with wires.
That being said, I've been preferring solid plastic frames. My bees chew through wax foundation and build all kinds of funny stuff on it. In the rare case that they build weird stuff on my plastic Acorn frames it's easier to just scrape it off and let them try again.
