Product review: Alanis is overrated. The whole world will find this out on Tuesday. (I already have- being a radio DJ is great, ain't it?) She cannot sing, she cannot play an instrument- all she can do is scream (and give us big headaches). Sorry, but you'll see what I mean. She's just another Top 40 act who means nothing to music in the long run. I would give her 0 stars if I could.
Ans: decrease

Review title: Works great for bed bugs!!!! Product review: Once I started using this with the duster I haven't had any bugs where they were previously feeding. I have been able to keep them from feeding and I've only seen around 10 bugs (which I killed on sight) since I started using this over a month ago. I will definitely keep this on hand from now on. I just wish I could've found this sooner than I did!!!

Review title: Deeply moved Product review: I have been a Jim Crace reader and fan for a long time and have always rated his novels amongst the most adventurous and beautiful. I thought his career must have peaked with Quarantine. How could any writer produce a more intellectually invasive and astounding work than that? But Being Dead has turned out to be his masterwork (so far) not because it is any better written than the others or more strartling in its imagery but because its emotional powers and its compassion are unequalled by any other story I have read. I could hardly bear to read it at times, but I certainly couldn't put it down
