First, they sent me the EZVIEW by mistake, but since I was allowed to keep it, I rate +1 for the service and flexibility.
Then, this is what I wanted: a wireless sound transmitter from PC to amplificator. Overall, there's no lossof sound quality (mp3) over the air. Only, the problems are the coverage (really, it DOESN'T pass through ANY wall, except a small wooden door). Also, the transmission gets interrupted when a person walks between the source and the receiver, even shortly. This had all been described in previous evaluations, but I had to see it for myself.
So, this is good if you have your pc (laptop in my case) in the same room as your sound device. Don't expect anything else. Good buy apart from this!
