We purchased an X-Trail hoverboard with bluetooth for £499 at christmas,are daughter used it for the third time after it had rained and the bluetooth made a strange noise and stopped working.We rang the store and they said we would have to pay £20 shipping costs to return the board which would be refundable if it was a manufacturers fault.We sent the board and had a call to say the chip in the bluetooth had got wet,we told them that are 9 year old daughter had used it after it had rained as the board was supposed to be water resistant and they said we would still have to pay an additional £35 for a new chip.We refused to pay anymore money so the board was returned un fixed,we are currently taking this up with trading standards as the board was mis sold to us.
