LONDON-Consumers have complained about retailer Game's decision to charge for demos of Sony's new Playstation Virtual Reality headset.

The firm is charging £5 ($6) for 10 minutes or £15 for a half hour in-store trial.

Game has yet to comment officially, but its customer services department has told customers that the fee is refundable against headset orders.

Sony is conducting a UK-wide free demo tour.

It said the decision to charge was "at the discretion" of the retailer.

Jamie Feltham from virtual reality news website Upload VR said he was blocked by Game's Twitter account after retweeting a promotional tweet from one of its stores over the weekend with the comment "this is not cool".

"I think it's not a good practice," he told the BBC about the charges.

"I work in VR so I'm interested in what's healthy for VR - and I don't think it's healthy to attach that image of it being a premium experience at that level.

"We should encourage people to see it for free, give them an amazing experience and then let them decide for themselves whether to buy it."

Twitter users expressed their frustration at the charges using the hashtag GameVR, which Game was also using to promote them.

"If there's one thing VR really needs, it's another paywall," tweeted game designer Mike Bithell.

"Disgraceful," said Bored...meh.

However some expressed their support.

"If you don't already own a PSVR, but might [want] to buy one, surely to goodness paying £5 to try it is much better than paying £350+ to then find out it... doesn't do what you wanted it to do," said a tweeter called KnucklePuck McDorian.

The headset, which Game is retailing at £349.99, is not as good as some of its rivals, Mr Feltham said.

"I think it's great, it's not on the level of Oculus Rift or the HTC Vive - but for the money it's a good system," he added.
