Wow. Either someone in Hungary is smarter than all the engineers @ BMW/Mercedes/Nissan/Yamaha/KTM/Honda/CanAm/Polaris/Suzuki/etc, or there are some seriously stupid people out there. Over 2200 of these things sold ($40 USD + shipping profit) is $88,000 in gross sales, and the only people who complained were the ones who installed it. Yikes.
There's sucker born every minute. Especially on eBay.
