Mlm2pro with concrete behind net?

Anyone have any experience with environmental interference or any issues with the mlm2pro? I don't have one, but I'm thinking of buying one soon.

I have a net cage/cube set up outside in my yard, it's currently aimed at a tall concrete retaining wall.

Set up looks like this: tee area, about 9 feet to the net impact panel, then another 2-3 feet to the back net wall of the cube cage, then another 2 feet to a concrete retaining wall (maybe 6 or 7 ft tall relative to where the mlm2pro would be).

Any concerns over interference or issues from the concrete?

Anyone have similar setups into a wall, or perhaps in a basement with exposed concrete foundation?
