5 out of 5 eggsGreat product

Pros: Plug and play, very simple. Works very well accross walls as we share TV from an appartment to another one in the same building (same floor). We save 50% each month on cable. I got it to run 24 hours during 5 days in a row and so far, I had to reconnect the receiver only this morning to get the sound to work.

Cons: Not much. Even the price was lowered by 100 $ when I purchased.

Other Thoughts: The whole process from buying to delivery took 2 days only with standard shipping.
