im with tamarack on this one, your service,quality and more people talking about your lift will make your product just basically more wanted than the others. if i were you id name them,sum-thing as the "the original jeff lift" or sum-thing like that just to show you are the first that made them. im an honest guy and i did my reserch before buying a kit, i wanted a kit that was cheap,very durable,easy to install and fits properly. from my research i have landed up to buy your lift kit for my need, i have seen those before but heard nothing from them on forums so i didn't boder buying them.
making a product and selling is not an easy task, id be pissed as well, like i said, you are well known out there, maybe trying to get the product announced a bit more as it is popular and the original ones, would make a difference. i wish you luck bud, if i buy another vitara or tracker, your lift will be on it
