Ignore the oddly low ratings. This is a five star product that brings much needed weapon diversity into 5e.
There is another review up here that states that this product does not provide a cultural context for its weapons, and is therefore incomplete. This is misleading - in fact, its brevity is part of its appeal. As a DM, I don't want a reference document telling my players an item's context or history - that's my job. If I want to make half-orc, half-dragon pirates forging katanas normal in my realm, then that's how it is, was, and will be, and I don't need a reference document document telling my players otherwise. Just like the original PHB weapons table, this equipment list gives you only the relevant physical properties (specifically, the combat properities) of an item and nothing more, and that's a good thing.
Rant aside, seriously, give this list a look through. The "super heavy weapons" (katana, bastard sword, full blade, etc.) give a much-needed buff to STR fighters over DEX fighters, and the new equipment packs make for excellent flavor drops when the party encounters a fallen adventurer. Overall, massive price of free, this product is an easy addition to any DM's binder.
