Negative Positive
Title: Be warned: this product does not work to cablevision's HD boxes.
Review: I bought this product hoping to resolve the loss of signal strength due to 4 way splitting.Bad news is that this product make splitted signal/noise ratio worse! I got cable guys came to my house for outside work (cablevision's wire problem) and asked them to measure the signal before and after this splitter during their visit, they told me that this splitter makes signal noise ratio worse and actually I should be better off using normal splitter!
Is the review positive or negative?
