Google is thy friend. Hi Points or nothing if not well discussed.
My summarized feelings as a Hi Point owner (who would be a former owner if they didn't pull such low resale value):
They are OK-ish. They are heavy for their size, and are very thick to come with a single-stack mag. Nigh on impossible to conceal carry one. Terrible sights and trigger. Ugly as sin. Slide is made of zinc which gives it a usable life span about 10% of the round count that of guns with a steel slide could handle.
As to reliability - it really depends. Some work great. Mine has actually never jammed the times that I've shot it. I have seen others with issues though (one guy brought one to one match I was in and I didn't see it make it through a single stage without 3-4 jams). If it DOES give you trouble they do indeed have a lifetime warranty, but with the cost of shipping a handgun if you have to use it once you're already approaching the price of something like a Sigma (which though no super-pistol, is in a completely different class).
Bottom line: if you absolutely, positively, cannot afford anything better, then it can be a working firearm that isn't quite the junk that the "ring of fire" (Jennings, Jiminez, etc) guns are. If you can though, IMHO you'd be much better served by spending the extra couple dollars and going to a S&W Sigma, Ruger P95, or even a Keltec P11 or PF9.
