I've made comments about this before regarding everything from solar panels, solar charge controllers, batteries, inverters... you name it. This isn't a new concept. All it takes is a business plan and some cash. No manufacturing plant or employees needed.
Just book a flight to Shenzhen and make a deal. There's thousands of Chinese manufacturers happy to sell you a pre-made product... the EXACT SAME product a dozen other American "entrepreneurs" are buying and reselling. Just arrange for them to silk screen your own company name and logo on it and Voilà... you're in business!
Moral to the story... if two (or more) products look eerily similar, shop by price.
