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.

Ex Output:
Bad review

The characters in this book are so incredibly dumb. They say idiotic things, like when the girl is trying to get into the library she's on her phone and someone comes out of their room knocking at the house who they think it is, then proceeds to tell her not to. Just dumb stuff. I couldn't finish reading this...

The CD arrived on time, in very good shape. The sound was so bad that I took it outside, mounted it, and threw away the CD. It went back outside immediately - as if having been returned from a distance of 50 miles. I had previously bought another CD to replace this one, but did not get anywhere with it. At least the other one works properly!Please do yourself a favor and avoid purchasing anything associated with this company.
