Gamers who feel ill playing Nintendo’s 3DS console have complained they are not being offered full refunds by retailers.
Thousands of customers have reported suffering headaches and dizziness after playing the three-dimensional machine, which works by flashing separate images into each eye, creating the illusion of depth.
But some are angry that they are only being offered partial refunds if they return the console to some retailers.
Sundeep Tailor, 27, from Luton said he started to feel unwell after playing his 3DS for just three minutes.
But when he took the product back to his local Game store he was initially offered a refund of £176.99, which is £30 less than the price he had paid.
Mr Tailor told The Sun: “I lost money in just 24 hours. There will probably be more people in my position.”
The Nintendo 3DS, which allows users to enjoy three dimensional images without the need for special glasses was launched in a blaze of glory last month.
Hundreds of eager gamers queued up for hours to be among the first to own one of the new consoles.
But Nintendo has been forced to defend the 3DS, last week announcing that the console was not safe for under-sevens, while also warning people to only play in 3D mode for less than 30 minutes at a time.
Some retailers, including HMV, are offering full refunds but only for a limited period.
A spokesman for Nintendo said the feedback for its 3D machine had been “overwhelmingly positive” with returns in single figures per retailer.
