To be honest, I was always a bit dubious about VR headsets - I saw them as a gimmick which was another way of extracting money from the gullible. But this made me eat my words! The absolute immersion that this provides is, frankly, amazing, and vaguely disturbing. Perhaps the feature I enjoy the most is the ability to integrate with Google Maps, and to wander the streets of most places in the world (Venice is my current favourite}. Many of the free apps make very effective use of the technology, and there are several reasonably priced paid apps available as well. Considering that this is a quarter of the price of top end mobile phones, it is, frankly, extraordinarily good value. It is great that, once set up, it runs independently of other devices, although it would be better if I had a faster broadband connection (5 MBps is not really enough, although it works OK) It does leave me feeling a little queasy sometimes, and takes a bit of getting used to, so the relatively short battery life (around 1 hour max) turns out not to be a major issue, as I need a break after that.
