Query: Terrible

Do not buy a Cyberhome product. I have the 1600 model and started having problems viewing DVD's and using the DVD recorder 2 months after purchasing the product. The customer service was terrible. I e mailed them several times without receiving an answer. The labor warrenty was only 3 months. I contacted them via phone, was on hold for an hour, and finally talked to a rude man who told me that I should have updated my firmware via downloading it from the wedsite. The download wouldn't work and he stated he would send me a disc. It never arrived. Awful company!!!
