[SML] Audience member phone cases

[dale]

I just heard about this product.  It is from what I can read from the vague website, pouches that you lock an audience members cell phone in to keep them from recording a show.  Some kind of field in the venue keeps them locked while inside.

Anyone actually used them yet?   Good, bad, or indifferent?
