Loads of people really don't like these systems, and I've got very used to this over the years but I like them - so here's a little video that chat's through them and then shows them going into a venue that has a particular problem - 1400 seats, one level and very limited height - and the VRX system really works. Hating them is fine - but for me, they do the trick and I can live with people being snippy and disparaging - a bit like Marmite - you love it, or hate it!
