only for Shoei helmet owners?

why a Shoei? thats just how an advertisement started that encouraged me to buy a Shoei helmet then the ad went on to say--No other helmet in the world can surpass the handmade quality of a Shoei............. ad in Sept 07 Rider magazine. I was also encouraged to buy a Shoei by the praising reviews. All this was about full faced helmets I only buy and wear half helmets. My question how can a company that can make such a wonderful full face helmet make such a poor or cr.... half helmet?? Or are their full faced helmets not all that wonderful just way over priced? Maybe Shoei does not even make their half helmet? I know I made a huge mistake. But i have never saw a Shoei helmet. I purchased a Shoei half helmet it had very poor linings and a thin strap that easly twisted, are the full faced Shoei helmet like this????
