Its a mediocre copy... Just another way to cash in on other peoples ideas really.
I dunno, both products are made and marketed by the same company, Adventure Medical Kits (AMK). So while I am inclined to agree that the revised design is less than stellar, I don't think it's a case of one company ripping off another's idea.
AMK took over production and marketing of the original Spark-Lite a long time ago, didn't they?
