[Q]: It worked for a month, I can't complain. The first problem was that my new monitor would not pick up the signal, so i tried several other sources before calling HDE support (which takes 3 days!). They said it must be some kind of interference etc. So all i needed to do was return the whole system and get another since we were getting no signal at all. They agreed to refund my money. Well that's when things got really bad as far as customer service.
[A]: Bad review


[Q]: Excellent for those of you who don't always go with the mainstream and like to take a different approach to their love life. Great read!!
[A]: Good Review


[Q]: This book is kind of funny, a bit dark, but still funny. Some chapters have been left out. So you don't know what happened at the end, and some are just not there. And there are a lot of typographical errors in it, too. But otherwise, it was good.
[A]:
Good Review
