It is always an interesting discussion point here. This is something i encountered when in sales.
Bang TV's are great value for money. They last for a long time, give great prescence within rooms, allow a huge degree of bespoke with colours, stands etc and some have optional modules. Most link to other rooms, making them versatile, they allow more speakers to be added - and if you dont add more speakers still sound better than anything else on the market. The picture quality is streets ahead of others on the market, use real elements of aluminium and glass on most giving a genuine feel to the product.
Bang offers backup service that others cant match, especially for parts and service. Many people used to quibble at the cost, then buy several tv's in the time that they could have bought and been happy with one Bangvision.
People waffle about HD this and Pixels that, at the end of the day, watch a movie on a Bangvision then go watch a Sony or something else.
Bangvisions have natural colours, natural movements, clear and defined images as well as unparralled ease of watchability.
Bangvisions also have fantastic contrast and colour as well as sensors for light so the picture adjusts accordingly. The processor also "forgets" to a degree the background of a picture so the front image is clear, giving a 3 dimentional picture element.
The anti reflection screen is also an expensive element of the Bangvision, being up until now blasted with lead balls to give this effect.
The Bangvisions also only use grade a+ screens. No other manufacturer in the world do this, apart from industrial screen users.
All this goes to make Bangvision, so you can watch good TV and you still quibble about the price....
