Milford safety net

I'm considering getting some sort of load restraint for the Challenger and found this product from Milford. Basically I don't like the idea of the full steel cargo barrier being there permanently and this safety net look like it is more what I need (put it up when needed, otherwise put it away and probably cheaper). Does anyone have feedback on them? What price, are they really working, can you still use the anchoring point in the roof of the boot to attach a baby seat, are they as easy to use as they say,...?
That's the link to their site (if I manage to do this properly): Milford Safety Net
Thanks,

Sly.
