Viper 151 Bluetooth Helmet

I bought two VIPER 151 BLUE TOOTH helmets from the Bike Show NEC 28th Nov 2014 and one has a very stiff flip front release button and I fear one day it will snap off, I asked the importer MOTORHART to exchange it as I have only had it one month and they flat refused , the warranty is with the importer and not the retailer apparently so if you have a problem its emails and phone calls and hassle , the intercom is ok but without the blue tooth these would be just cheap £50 helmets so buy better from a good retailer who cares and steer clear of VIPER HELMETS .....
