Question: Title: Not up to par Review: Well the tank was delivered fast and that was great. The tank also looks good with a snazzy logo...but who cares. If I fill it up and don't use it in the next day or two it drains. I was hoping that it just needed a break in period or something but it hasn't gotten better. I have been every where trying to find an air smith to fix the leak but I have had no luck. I guess I will try and return the tank but I loath the idea of returning to an online company. How I wish I had gone to a physical store so that I could exchange it without any problems. [...] There is a lot of great paintball items you can save money on by buying online but from now on I won't be getting tanks online with only a 5 dollar savings the hassle is not worth it. I'll pay 5 dollars more for peace of mind. Does this product review convey a negative or positive sentiment?

Question: Title: not so bad Review: Catilina's Riddle was not the worst book I have ever read. The story itself is very busy, which helps because if you're not too intrested in one aspect of the book, it quickly switches to a story line which hopefully suits your taste better. The book is classified as a mytery. As a mystery, I must confess that the book is a needed breath of fresh air which branches away from the normal whodunit. The plot is very thick, and resides not only with a family, but with an entire city at war with itself. IN ALL, the book is pretty good, but like most books of it's size, it can bore the reader with an occasional lull. Does this product review convey a negative or positive sentiment?
