Bought 2 Vipers, one for me and the second for my wife. Second week had to return mine for a replacement as the right speaker didn't work, several months later returned both helmets to have the Bluetooth replaced..one circuit board fried the other the charging stork in the centre broke. Week later and my Bluetooth refused to charge. Have now sold my wife's and returning mine for full refund. Bought Schberths which i should have bought in the first place.
Vipers were noisy and Bluetooth although easy to pair was too quiet when riding and we would have to shout...
Better off paying little bit extra and researching other helmets and not to see the cheap price decide you. I have found cheap item turns out to be expensive in the long run!!!
