I originally bought this about three months ago, and only commented rather than leaving a full review. Since I've had three months to reflect (and a few minutes to write) I can go into my feelings in some detail.
First, I should mention I got this at half price during a promotion. It was, more or less, worth that $1.50 because, as I said, you can't buy a good d20 for that. (given what I spent backing the Dispel Dice Kickstarter ... no, I don't want to think about that one) I mostly wanted to see what it was, and that was worth a buck and a half to me. It's worth taking the price it might be at any given time into consideration when you decide if this is something you want.
I would describe it as "shovelware". Like the old CDs whose publishers used to round up everything free, shareware, or dubious, load it onto a disc, and sell it for a few bucks at computer shows, it's in many ways a disorganized heap of stuff, piled up together without rhyme or reason.
There are certainly thousands of names, but, for example, the names for people do not indicate culture, nationality, or even gender. (though one of the suggested names for giants is "Gender", which makes you think ... unfortunately, it makes me think about what database the author might have scraped) As I said in my comments earlier, aparently Aristomachos and Arihelva might be next-door neighbors. Without any of that information, it is much less useful than the many name lists that are for sale here on DriveThruRPG, or even the innumerable free baby name lists you can find online. You could write down lists of syllables and throw dice to choose them, and get names at least as useful as these.
The formatting makes it painful to read. There is a reason everything from newspapers to books do not center all their text, and that reason is not that they're unable to; it's that centered text strains the eye. You can't just pop right to the next line as you read; you have to look for it, it's over there somewhere. And this product has pages and pages of that.
In my opinion, it's worth a buck and a half for the inn names. I just really like the Furious Llama! Most of them would work pretty well for any fantasy setting, or potentially historical or other genres, and you're not going to be tripped up by not knowing where and when a name belongs as with the human names. (or Gender the Giant!)
I think if the author were to discard everything but the inns, left-justify them, and equip them with numbers for easy dice-roll selection, that might be worth the asking price. As it is, however, it is not.
