glass sound booth

Hi friends,

I've always disliked the typical vocal booths that are mostly dark and filled with foam so I'm contemplating getting a dual layer glass sound booth as the ones that are used in office work. I know the isolation works great but am concerned about the acoustics inside since there would be 2 walls facing each other of glass (even though I would not mic in that direction). These are the kind of booths I'm considering:

Have you had experience with this kind of booths? My instinct tells me if one of the walls becomes a problem I can cancel it out and still have the second unobstructed wall or most of it.

I'd appreciate your feedback on this!

TY
