I'm thinking of buying them and trying it. I heard about it from here:

Thoughts?

I have used them. I added them to some home made snoots and they work well. I have ordered from him two times. shipping was fast and products are as described. Not sure this is what you need but i am happy with the product

do you have any photos that you've used these grids on?

I have never used it as a key light. Mostly to add separation on a back ground between a product and the back ground. I need to think of a specific shot where I used it. I will look for something. Actually, they look similar to the second image on your link to studio . net. Just a faint separation between the model's head and the back ground. I have also used it to fill in the front of a small snoot to control the light on part of a product.
