Many factories use a Lieberman to rapidly apply the binder to the filler bulk by less skilled workers. These bound bulks usually go into a cigar press (which reduces the ring gauge). If the wrapper is subsequently applied by hand, which is usually the case, they are still called "hand made."
Unless you are a gadget collector, or hopelessly clumsy, there is no advantage to your using a Lieberman device (or a cigar press, for that matter) for home rolling cigars. It takes 30 or so separate, tested attempts to successfully hand-roll consistently smokable cigars that you'll be proud of. (I'm saying, roll one, rather than ten, then smoke it, and learn from that test.) Beauty takes a bit more practice.
